There is no groundhog season in Wisconsin. If I want an opportunity to hunt in the year to come, I need to reach out to my neighbors.
The best way to get a positive response is with a person to person interaction, unless I just show up on the door unannounced. I hope to get achieve a higher success rate than the Jehovah's Witness. The letter serves as an introduction and a request for that person to person meeting.
I am a fairly strong introvert. If I do not get a response, my first choice would be to crawl under a rock or maybe drive to Minnesota and hunt on public land. My intent, however, is to force myself to follow up, at the very least, with a phone call.
