I would start asking neighbors for permission and roosting them at night and early in the morning with locator calls and ears. They sound like they have a daily routine, now, which WILL change, especially as the hens get bred and start nesting. After finding where they roost, I'd look for their strutting areas and their feeding areas. I'd also be after as many of the neighbors as possible for permission to hunt 'em and when I would be talking to the neighbors, I'd ask what they have seen of the birds. A lot of people will say things like--Well, those birds hang out in my back yard all afternoon and then go over to Jim's woods-- or something similar, if you ask if they've been seeing turkeys, and if you ask around enough, and spend time scouting yourself enough, you should be pretty familiar with their daily routine, or variations thereof, by the time the season opens. Familiarity is important, because the more you know about their habits and routines, the more likely you can guess where they might be at different times of the day, and make a hunting plan accordingly.

I would not limit myself to only one opportunity by camping out on the ten acres your father owns, though, even if it is successful.

Good luck.
