Great story. I added a comment.
I always ask the bikers if they're doing okay. I know I'd hate to be left out there without enough water, and I always keep more than enough in my cooler to go around.
Over Labor Day this last September, we came across a lady running PSM. She was still going up the trail at the Wedge when we came up to her, and the 12 oz plastic bottle she had was empty (of course). We gave her another bottle and made sure we kept her empty one so she wouldn't drop it on the ground.
The bad images people get about offroaders are from the idiots who take daddy's truck up into the hills nearby and trash everything. 98% of the people out in Moab on the trails are the nicest people you'll ever meet and will give anyone a hand.
I had fuel pump problems last spring on Gold Bar Rim. A full-size Blazer asked if I needed a tow, and before I could answer he was getting his strap out. He ended pulling me all the way back to the highway. When I offered him some cash to say thanks, he flat-out denied me and went on his way.
