Its happening everywhere. Its funny how on the ice guys walk by and check for blood stains on the ice , or my favourite is when they start with all the right questions one after the other(any luck ,how deep are you fishing ,what are you using) and at the end they setup right beside you.
Fishing on a boat (jigging for walleye) is the same crap. Guys see you on the lake and your on the fish, next thing you know they are right beside you. It sucks but its becoming a norm everywhere.
