People who tell you they are gonna go hunting with you, and at the last minute back out. Especially the ones that you have scouted for and put forth some effort to ensure they have an enjoyable experience. Then call you the night before and say they are not going to be able to make it.

Or like my buddy never takes care of his equipment, he shoots his bow 2 weeks before season, has no idea about form aor anything. His strings look like crap his bow is loud, he just dont care. Then his muzzleloader is always dirty and messed up and wont group the size of a pie plate at 50 yards. Then on opening day of rifle season kills 3 deer at one time then goes back the next day and kills 2 more (which is illegal in this state).

Somebody who thinks they have to kill more deer than you. I hate somebody who turns deer hunting into a competition, they shoot anything they see and proclaim to be a better hunter than you because they killed a yearling doe or a button buck. Great white hunter shooting baby deer, heck with a corn pile and a 30-06 you should be able to kill all the baby deer your heart desires...

Sorry it was so long,
