15 years ago, it was a Ground Hog Gold Mine here in eastern PA, namely, northern Berks County. Access was no problem, ground hogs galore!
Then came the overdevelopment and the change in farming practices. Where I once had 8 to 9 farms, I am down to 3. Of those three, less than 50% of the fields are huntable for groundhogs due to changes in farming practices, i.e., planting in strips, planting mostly corn. Gone are the long rolling hay fields of yester year.
Some fellow shooters claim it is still fairly good up around State College, but I cannot attest to that since I never hunted up there.
The only reason I go now around here is to get out in nature, take snooze and enjoy the outdoors. If I get a shot or two, it's a bonus safari.
