I'm from rural southern MD. Ground hogs started showing up there about 30 - 35 years ago. Almost turned over our tractor when I hit one of their holes.
I suppose in 2017 & living with close neighbors, trap & relocate is the best way. I'm sure the law has more to do than chase you down over a pest & moving to a more rural area. They would have to "catch you in the act" before they could write you up.
I always let the trap hang over my tail gate, wearing gloves & using a stick is how opened the door. Be careful, they're normally pissed when they come out.
