I saw your post looking for people for a grand canyon trip. I'm interested!
I'm a 35 Y/O guy with some big water experience. I've done Deso/Gray at high water, Westwater several times, And this spring I did the Main Salmon at 57K. I've also done some smaller rivers.
I work as a Firefighter/EMT. I'm a long time rockclimber and outdoors guy.
I can give you references if you'd like.
I live in Denver.
