Here's a few. I reserve the right to add more as I remember them!
1. Killing a lot of deer is a lot of work.....and is NOT to be confused with necessarily having "fun"
2. DO NOT hunt when it's hot.
3. NEVER, EVER nock another arrow if you've shot a deer and you didn't see that deer go down.
4. Jeff's effective range is shorter than he thought it was.
5. The Rage 2-blade is an awesome head.
6. There's NO reason to be in a hurry. My deer will show up....and patience is a virtue

7. Never invite someone to hunt with "rules". They're either a good enough friend to be in your woods with carte' blanche shooting rights....or they're not.
8. My Allegiance will be hard to retire for the '08 season.
9. Your season can take a WONDERFUL turn in a matter of seconds

10. Big does have more meat on them.
11. A good knife is a WONDERFUL tool.
12. Easton a/c/c/'s, while expensive, are virtually indestructible and will more than pay for themselves in arrows NOT broken in deer.
13. Injuring deer sucks, BIG time.
14. Some things are better kept to oneself.
15. There are 3 types of hunters: 1) Those who have injured or lost a deer. 2) Those that have injured or lost a deer...and will not admit to it.. and 3) Those who haven't had enough shot opportunities to be a #1 or #2
16. A 200# deer, amazingly, is a pretty easy drag.
17. Deer hunting, in perspective, isn't that important. Life situations are, and we've all witnessed some of that in the forums, this season.
18. A little bit of luck will trump a LOT of skill
19. PA is a BEAUTIFUL state. Go back, often....
20. Hunt less. Hunt smarter. Have more fun.
