I carry when I go to the Glasgow dog park, but if you're looking for a good place for dogs, I recommend the Dog park in Middletown on Levels Rd off of Rt 301. 5 acres for the big dogs and 3 acres for the little dogs plus doggie drinking fountains. I carry there and I know I'm not the only one.
By the way, 301 north of Middletown is a mess.
