a lot of personal party questions. i have been down a few times.each trip is different. one trip we worked hard covered like 18 to 21 miles a day, and we had 6 full layover days( i am a big fan of the layover. a lot less rigging, longer days on the river though. a lot more hiking and seeing the canyon world). we got up early AND FINISHED IN THE DARK WITH DISHES, SHORTER DAYS in the fall. this was a november trip. u r allowed more time in the off seasons also, we did 23 days. there is not always a lot of current in the inner canyon. it divers to the bottom like in westwater canyon. u r following the winding small current with huge eddies on both sides, a lot more rowing and less floating than i had originally thought. we used canyon r.e.o. for food. they did a great job. i do not think that i would want to go in the middle of summer. it seems like it would be an inferno. it was hard to get to sleep for me even on the early oct launch trip. the rocks held so much heat. i would have to get in to the river before i went to bed to cool down. bring sheets to sleep in. did not even want fires in the evening it was too hot to sit close, we had very big circle (far away) around it the few fires we did have. even taking out after thanksgiving, i did not need the 0 degree bag. never even frosted after the put in. there is a much better chance of getting a permit in the more off season, and less competition for camps and after nov like 5 no more motor rigs. we also had a rule of helping to set up the group stuff: kitchen, groover , firepan before people ran to find their ideal spot. there will always be the few who think their needs r more important than the group. this was the hardest part. group interworkings...there will always be some conflicts on a long trip with the same people and their same issues stuck in a small space for three weeks... everybody try to be extra patient with others. we had like 5 kayackers on our trip and 4 rafts. there was a lot of rigging, and being one of the captains got stuck with more than my share. while lazy kayackers sat on the beach and stretched or wandered. for future i would want each kayacker to be assigned to a boat to help with rigging. bring plenty of lotion. wear gloves when rigging.( saved my hands!) have a great time.
