ahhhhhhhhh yes the unspoken behind the scenes psychological warfare with the hunting buddies!!! The true test of will power. Don't be shy you can tell us that you ARE competing with him and want to kick his butt. [:-] Let him have the sighting numbers and doe/small buck etc..... If I were you I'd hold out and shoot yourself a MONSTER the last hour of the last day of the season. He may be smiling now, but you'll have the smile for the next 11 months.
I know what you're talking about and have the same situation with a buddy of mine that hunts with me a lot. (except I'm on the other side) He has seen 1 doe while on stand in the first 3 weeks of bowseason. I almost don't want to tell him what I saw on stand after a hunt.(but I do) I can tell it's just eating him alive. But, I'm not going to rub it in too bad cause he's the kind of guy that will stick a 150 class buck the last day.
Hang in there it'll pick up for ya and be that much more rewarding when it happens.
