Yeah your right, persistence and patience will get you a bird more times than not, that's my thought anyway.

Change things up one day, sleep in and go in later....the season is nearing the end and the birds have changed their patterns some. I find sometimes a change in my schedule is just what does the trick, you never know.

As far as guys cutting you off, I've had that happen a handful of times in the last 3 years and it is very frustrating, makes no sense to me, I'll leave and hunt somewhere else for an hour or so then come back later and try those birds again.
