Lessons Learned so far...

Truly, the following points should be shared by anyone coming to Rwanda. But then, who would ever undertake such an adventure without the full support of multinational corporation with a department of staff dedicated to giving accurate advice to valued executive staff? 

1. If you live in urban areas, you don't have to pack a ton of DEET bug spray to ward off mosquitoes.  I have heard only one mosquito buzzing around my head.  That was when I was in a remote part of the Eastern Province at dusk.  I was wearning bug spray and a head scarf but was terrified that I might be dead from malaria within 24 hours.  Based on warnings from the Travel Health people at home, I was thinking that maybe malaria-carrying mosquitoes don't have any buzzing sound and can sneak up on me (someone who grew up in Muskoka).  Where are all the so-called mosquitoes???
2. Do bring the chlorine dioxide mixture to treat your own water which has been filtered already of any visible contaminants.  None of us have suffered any of the dreadful, dysentry-type symptoms that we we warned about by Travel Health officials back home.
3. Buy from small farmer huts located near a local Supermarket. Can you remember bringing home farm fresh eggs in a brown paper bag? Just bought a huge bag of green peas.  I've never tasted peas as full-flavoured as good in Grandma Goltz's clay pea patch. Prices are great and food is fresh although it probably needs to be treated.  For precaution, soak this food in a strong concentration of chlorine dioxide before handling in the kitchen or boil it for at least 20 minutes like I did the peas. 
4. Understand fully what you are getting for Internet service and how to download more time.  Look for promotions among the local service companies.  For example, after gobbling many megabytes of data thinking that our service was 'unlimited', we have figured out that we should have topped up our daily quota before it ran out.  Also, 'browse all day' in fact means maximum 2 GB which we ate up within hours.  Furthermore, we pay about $2 per day for this promotion but we have to reinitialize the service each day after prepaying for several days at a time.  This sounds pretty complicated to me.  Why not give us unlimited for a set number of days?  "Unlimited by this particular service provider won't be available for 2-3 months but at least its high-speed service is consistent - when it's working.
5. Make sure a portable internet stick for your Apple laptop is compatible.  We were forced to buy a WiFi router for our Apple laptop and that resulted in the strange payment arrangement described in Item 4 above.
6. The easiest access is an Internet stick with unlimited access for about $17/week.  However, you have to go back to the service provider to have more time added to the stick.
7. You can buy local SIM cards for your mobile phone and purchase little vouchers for about 3 dollars which give you a couple hours talking for outbound calls.  Incoming calls are free.  However, make sure the voucher has not expired especially if you buy if from someone standing on the street corner even if they are wearing the service providers uniform!  Went back to that bunch of streetcorner vendors and they showed me all the cards are dated 2011.  So, one of them took one of the vouchers and uploaded more time for me.  Problem with my earlier voucher was that the "scratch" strip peeled completely off on me taking the voucher code digits with it.  Unfortunately, I didn't decipher the digits accurately and thought the card was expired.  
8. In humid tropical climates, if your electrical water heater stops working, the metal plug could be corroded and needs to be replaced.  This we discovered after four days of cold showers.  Mind you, "cold" in the tropics means  "tepid" in Canada and at the most, just stimulates the lymph nodes.
9. When applying for Resident Permits, make sure you understand completely all the documents required.  I don't know why this process hasn't been completely documented.  The only thing I read was the need for a police clearance.  Believe me, there's always more so be prepared.  For example, you have to be able to prove your relationship to the person apply for the Permit if you are applying as a Dependent. 
10. Last but not least, take a week to sleep as you adjust to this fantastic warm, gentle climate in the tropical highlands of East Africa.  Life is simpler here than at home and a common phrase I keep hearing is "no problem."
