US dollars

Damm. Knew I should have done this sooner. I just sat down and worked out the tips for the trek and the safari, plus the US dollars for the rental of down sleeping bag ($4 a day), down jacket ($4 a day) and poles ($2 a day) and of course I don't have enough small US bills. I thought $50 would be enough but the trek tips alone eat that up. So I'll have to run to the bank first thing tomorrow and see if I can get more.
