If you look at the banners behind Shane and Otis in the gym, you will see that the school they are at has the initials C.H.S. and has a Cougar as a mascot. In reality, the school used for these scenes is Newnan High School (NHS) that does have the Cougar as their mascot.
Goof (though possible explanation): The suicide that ended up as a Walker had its legs eaten at by other zombies. It's made clear in the series that the zombies only eat the living and not the dead. He had time to produce a noose, get up a tree and jump so there shouldn't have been any Walkers nearby while he died.
It's possible the camper was chased up the tree by walkers or walkers caught up to him by the time he was ready to hang himself, so once he jumped the walkers would've started eating away at him, and likely stopped when the body lost the scent that attracts walkers - body heat/etc - likely why he wasn't pulled down - by the time his legs where eaten the body finally read/smelled dead to the walkers and they abandoned it.
Patricia: (to T-Dog as she is sewing up his arm and referring to the medicine he took) Merle Dixon's clap is the best thing that ever happened to you.
Rick: (trying to justify why they should go on to Lori) There is still a life for us, a place maybe like this. It isn't all death, out there; it can't be. We just have to be strong enough, after all we've seen, to still believe that. Why is it better for Carl to live, even in this world? He talked about the deer.
Daryl: Look at him. Hanging up there like a big piñata. The other geeks came and ate all the flesh off his legs.
Andrea: I thought we were changing the subject.
Daryl: Call that payback for laughing about my itchy a**.
Daryl: (finds a walker hanging by a rope, reads off a note on the tree) "Got bit. Fever hit. World gone to sh**. Might as well quit." Dumb*** didn't know enough to shoot himself in the head. Turns himself in a swinging piece of bait. And a mess.
