I searched Connecticut and found two entries. Keith Kratz of Windham County, and Joe Teschendorf of New London County. A fellow in Calgary will swap deer and elk hunting there with caribou hunt in the Northwest Territories. A fellow in California will swap a whitetail, turkey or wild hog hunt there for an elk, mulie or blacktail hunt. A Pennsylvanian will swap a ground hog hunt for a prairie dog hunt.
Entries list an email address as a hotlink.
If you are a prairie dog hunter and would like to try ground hogs, use the link and send email. You arrange with the other person to visit him for the hunt he offers then he visits you for the hunt you offer. There's a section for contributors to submit hunting anecdotes that become visible for all to read. But that's separate from their online hunting magazine with professional writers. There are web sites that address broad outdoor interests and, naturally, include hunting.
