Hmmmm, there are a lot of ways to get into the dogs. The best way I've found is just to start hanging out at the right places. For me, here in Minnesota, I find it best to go out to a bar or the local gas station... where all the old farmers hang out. I've gotten about 20 places to hunt in just one night by doing that. Another way is to contact your local game warden (here in MN it's the Department of Natural Resources) and ask if they have any info. Other than that, just drive around with a locater call in your vehicle. Drive the back country roads and occasionally stop and let that sucker howl. That should give you an idea of where they're hanging out.
