I hear you. That seems to be about the going rate from what I've seen and heard. If it was a good field, with food provided, and the field isn't crowded with people then that seems pretty fair. That said, if it was 125 I'd say no way too expensive lol. The average person doesn't have a place to go, or own the equipment to do their own which is why public fields are a $#!+ show. Not dove hunting isn't a option for me so if I was in either of those boats 100 bucks would be a steal if the field was as mentioned earlier. I wouldn't be doing it every weekend though.
Seems when I was a lot younger it was 50, in some cases 25, but usually 50. There were some higher but 50 was the norm so if it's only doubled in all that time then that's actually surprisingly low considering how hard it is now to find a private spot for ANY sort of hunting.
I hunt public the first 3 or 4 days of season and what I see and hear in the field in those few days makes me so appreciative of my place and a few others that I hunt later in the season.
