This was me two years ago!
This photo makes me laugh endlessly now.
I had no idea - I didn't properly inflate the raft, and we(I) didn't understand that 1 person drives! We cartwheeled on down in the sleet/hail/rain/wind both trying to steer. It was 2 stooges!
I tell people of this first adventure and the reaction is always: "People had to be laughing at you" but no, there were no people there. It rained hard with 50+ MPH winds the night before, we got soaked, and we were pretty hardened campers/backpackers if never before overnight rafters at the time. We did talk to Mr. Cooper for the permit and he warned us the weather would be the same for the next 3 days, which is why there were no witnesses. We'd seen the weather an knew.
I had just bought my first raft, but had been reading about/researching this canyon for years. I got the raft after the permit lottery, but it was flowing that April, before lottery season when you can get a walk-in permit. Not going then meant possibly not seeing this river for another year.
We luckily had no problems on the river and the scariest/most dangerous incident occurred when I was nearly struck by a rattlesnake (in 40 degree snowy weather!!). Lucky for me the thing must have been severely slowed by the cold! It had energy to buzz and was inches from my unprotected foot (note the wool socks in tevas).
I would never recommend such idiocy to anyone, but wouldn't take that trip back for anything!
Hope you got a laugh! I'm much better now I swear!
