RE: first buck on my own...
congratulations on the hunt. nice buck. I too am just recently getting back into hunting (this will be 2nd year after a long hiatus)....the bug definitely bites hard, but feels sooo good!
I wouldn't worry about folks who say 'let em walk'....that buck is a nice way to get back into things, and it comes with the biggest buck bragging rights for you & your friends' hunt....from here you can always strive to improve your hunts each year.
I give ya a big high-5!!
