Got a note from our pal Rick in Alberta Beach. (Don't boggle, it's a beach on Lac St Anne, the holy lake for pilgrimages by prairie Cree people.)
Seems there was this guy who bought his first boat, and for some reason picked a motor boat instead of a kayak. He got a little advice about how to launch his new boat from a ramp -- "Don't let the trailer get too deep when you are launching."
Should have got a little more advice, I guess.
This is why I like launching kayaks better than launching motor boats!
