One year me and a bud were kayaking Browns in super low levels in September. Beautiful autumn day in the canyon and we thought we had Browns all to ourselves that day.
came to one slot, might have been some where around Toilet Bowl and a commercial 14 foot paddle raft came along behind us as we were really going slow.
The slot was tight for a kayak and we looked at each other and grinned wondering how the guide would get by.
Just above the slot he had all the custies set on one tube, used his guide stick to control the raft thru the slot, sat the raft back upright, looked at us with a big grin on his face as we saluted him big time.
You should not have major problems, just be ready to take it easy and have fun.
