Where are you located? I wouldn't worry about not having experience and afraid to ask farmers to use their land. I wouldn't think they would mind as long as you know how to use your gun! Your 33 yrs old, its not like your a punk kid who don't know how to use a gun and wanting to use someone elses land to shoot up. You could offer to help them do a little work around the farm in exchange for using their land for hunting. Just curious as to what guns you have picked out. Well, good luck hunting and welcome to the site!
