First let me apologize for the fact that these were taken with a canon. I was kind of busy at the time so was unable to take any decent shots with a PENTAX. Feel free to blast the quality all you want.
At least there are no copyright restrictions. The reason we were sitting inside the raft instead of on the edge as is usual, was because this particular rapid is a class 4 and known for causing people to be tossed out. I think it was just because we were old folks. Wasn't easy getting back into position for the rest of the trip either.
You may also try and guess which one I am - took a brave person to allow these photos.
