I have been with no pads and know people who skate it a lot with no pads, there is no attendent or guard so you do not officially have to wear them. There is a police station near by which could check out the park, but do not. All the metal ramps are worn and old but still plenty skateable, they get very hot in the summer.
Pretty decent park, nice mini-pipe, all metal. Gets packed after school gets out and right next door to the Police station so you sometimes get trouble with not wearing helmets. But otherwise a very descent free park.
