We go just about every weekend and sometimes during the week. I volunteer taking out trash, picking up poop or whatever needs done. So I am pretty familiar with it.
Saturdays can be a mad house. I have seen all the parking spots taken up and people parking on the grass. Well until they put up signs. I have seen up to 50 dogs running around. But if we get there by Noon or so it's not so bad.
Its located on Grand between May and Portland. It's right by the Hefner Expressway. Unfortunatley Grand doesn't have an off-ramp, so I get off Hefner Expressway onto NW Expressway and make a right on Portland, then make a right on Grand. You just need to make sure you get in the right left turning lane at the light when you get on NW Expressway because Portland is the next light.
