The "surveys" that really irritate me are the ones that ask a couple of questions and then ask for a donation. NRA is notorious for that. Police groups as well.
Back before it was generally known how badly LaPierre was picking the NRA's pockets, if I had a few spare bucks and they asked, I would donate. No more, and not for a long time now.
First, WLP & co are still in charge (last I knew) and second, my personal situation changed and I no longer have spare bucks to give to anybody, noble cause, or not.
No problem, people drive cars into lakes all the time.
Long time ago I drove a truck camper over the really TALL bridge at the mouth of the Columbia. Wind was really pushing me around and I was more than a bit "puckered"...oddly enough what I thought most about was not if we would survive being blown off the bridge (it was a LONG way down!) but if I could get divers to find and recover my guns in the camper before they rusted solid. priorities, right?
The Columbia River from the bar up past Astoria is "only" 43 to 55 feet deep; but I bet divers would worry about the current and poor visibility first. I suspect that "a big claw from a crane on a barge" would be the usual method of recovering wrecks/clearing the shipping channel.
