RE: Who is the "sleeper" this fall???
Mobo, GMMAT, and Rob.
These were the first three to come to mind, though I've seen a few others posted who should be considered "sleepers" as well.
As for me... I'm switching things up this year and sticking to Mulies in the early season (unless I happen to spot a monster whitetail this summer). I wouldn't hold too much hope for seeing me tag a "trophy" this fall, though I don't plan on shooting the first dink I see.
