If you do come to Panama, we would be more than happy to set something up for you. And even if you don't do a trip with us, we can help you out with shuttles, river beta, and where to stay. Just for a teaser, check out this page on our website to get an idea of what we have to paddle:
Boquete Outdoor Adventures » Rivers in Panama’s Chiriqui Province: 35+ and Counting!
This is not even a complete list. Like I said, whether you are trying to do it on your own or you go through us, we will be happy to help you out. You can contact us ahead of time or stop by our office in Boquete (in the Los Establos building near the center of town).
By the way, Jim Omer is a partner in Boquete Outdoor Adventures (along with Jack Palmer). They joined us earlier this year and we are very happy to have them!
