[/QUOTE] Rode last year for the first time with two guys who did it the year before and they had me buy the rugged radio brand of radio. LOVED IT. And would highly recommend it for bike to bike comms. +Speeds up the ride, less stops +Lowers stress thinking about "where are they, did something happen?" +Day two, early in the morning, down a sand wash, into the sun with 500 riders is a lot of dust and very limited visibility......Our 3rd rider passed us while we were peeing and didn't see him go by....thus the during the radio checks when he fell out of range, we kept slowing down thinking he was behind us. Turns out he was in front of us. And it took a long time to get back together again. (We made the mistake of not communicationg the pee break because we "thought for sure we would see him and he would see us. Neitther did! Visibility is probably less than 5 feet in that situation. +Plus they are just FUN +Also can mention washouts and other cautions on the fly. Radios saved a massive wipeout.
