No such thing as a ‘dumb’ question! You’ve obviously put some thought into it.
I’ve informally had several discussions at various ‘local establishments’ with the bar keep, front desk staff, etc. and they’ve put me and travel partners on fish with some maps marked up on a napkins!
Local resources are all over..hardware store, bait shop, gas station, etc.
I HAVE found that they’re most willing to help and even get MORE specific on fishing locations at the point of purchase..i.e. booking a room, purchasing a dinner, etc.
“Oh by the way, we’re going to be doing some fishing locally and if a guys wanted to located a few {target species} where would be a good place to start?”
We’ve always gone back to points of information during our stays and graciously let them know our results.
