For starters:
Heard a couple argue about beaching kayaks and about loading them for 15 minutes at the boat ramp.
I've had a fool tell me and my wife "you're using bass gear to catch trout, that's messed up, that's so wrong i should throw you in" meanwhile he was using live bait in an artificial lure only creek section
Some guy said to me "hey you let you wife drive your boat?"
Let us know what you got...
