About 25 years ago I was going to Virginia. There was an RV in front of me and I watched the back axle collapse out from under it. It rolled four or five times, all kinds of things flying out of the windows, bounced down a ravine and ended up face down. It was sitting there smoking and steaming. Shit all over the Interstate.
I stopped. Another guy stopped. Young black dude. Everybody else just kept going. We got to the RV. There was a guy laying on the ground next to it. Looked like he'd come through the windshield. The back screen door popped open and an old lady who was bleeding all over her face and arms started trying to crawl out. We pulled her out and then he went down into the RV and started handing kids up to me. I just kept sitting them on the side of the hill. Four or five in all. The guy on the ground staggered away and crawled up the hill. Turned out it was grandparents and their grandkids. They counted the kids and confirmed they were all there. About the time we got them all out, the propane range inside it started burning. The thing caught quickly.
I shook hands with the black guy, we got in our respective cars and left. Didn't even wait on the cops. My now ex-wife screamed at me for being stupid and "getting involved." She didn't talk to me for about 200 miles. Blessings.
Would I do the same thing now? Probably not. Would I have done it then if the RV was already on fire? I don't think so. I'd like to think I would, but my hunch is that if I came across the same situation today, I'd stand there with my cell phone, take some pics and call 911.
