Always nice to find a little surprise that you never realized was there - in this case, the park that is nestled right inside the 485 loop. You may never know it is even there unless you are looking for it, as it's a slight drive off of Pleasant Plains (and I do mean small - not even a quarter mile - but hidden by trees so you may never see it), but it is worth taking that small turn.
One in the park, there is a small lake, a couple of picnic shelters and some playground equipment as well. This is not a monstrous park where you're going to spend the entire summer afternoon playing in the grassy fields or anything, but it is an excellent spot and the trees provide for some nice shade, so well worth checking out.
