34 is the count. I only count rivers like the Colorado once, even though I have boated on it in three states. I am a rafter/multi-day tripper, though have been bagging some new rivers on my SUP. Most of my international boating has been with my Habitat for Humanity crew and with commercial outfits.
Sri Lanka was certainly an adventure. Here is the link for where we stayed in treehouses before and after paddling. The guide spoke no english, though was certainly a "boater". White Water Rafting in Sri Lanka, Sri Lanka White Water Rafting Kitulgala
. still looking for photos of that trip.
In Uganda, I paddled the Nile once with the HFH crew and again a few weeks later on my bday (I backpacked around Uganda and Congo for 5 weeks after the HFH build was complete). My favorite pic below, with a single person standing as we crash through a wave (that's me)!
