I met some friends at Pebble Park to take some photos. At first glance, it seems to be a rather small park, tucked behind a nursery near Eastern and the 215.
There are a couple shaded areas to sit and eat, a playground and a pretty awesome water feature that even I had to play in. The parking lot only had three spots but you can also park along the street. You can walk along a paved path to get to the rest of the park, which is where we saw quite a few people playing with their dogs.
The main downside to this park is the of a lack of a bathroom.
P.S. Please pick up after your dogs if you go!! No one likes to step in dog crap.
