We did the 54 miles in 22 hours last spring. We camped at truck stop, RR just past diamond. We boated past separation (don't have access to info right now) to a camp at RL with a hualapai outhouse (f'in gross!). We barged up there and floated the night with the full moon. Keep in mind it will be MUCH colder at night, on the water. At least in march, and we had been having days in the high 80's maybe 90's. Put warm clothes on before you get cold and figure out a way to make hot drinks. Night float was amazing!
We floated below separation to see our speed with gps. We were getting 3 mph and that's what we used to time out night float departure. We planned for an 8 am arrival and I think we were within 15 mins of it.
