i hydrolocked it when i went through too deep of a puddle a bit too fast... i was just about to leave the park where we were wheelin completeley unharmed and i had swiched into 4 hi from 4 low, and decided to go through some water holes i had been through before and i just made too big of a splash. it wouldnt have been too deep if i was just creepin through it, and i was within 3 feet of the end of the puddle that was like 150 ft long. and in 20 more feet, i would have been on the main road. i think ill stay away from puddles untill i have a snorkel from now on.
