ok, screw hines park... i have the ideal place.
my parents live in a neighborhood in west bloomfield called "westacres". it's around commerce road and keith road. they have a private beach on middle straits lake. there's tons of parking, picnic tables, a beach, a small pavillion, a playground if you bring kids, tennis courts, and a baseball diamond. best of all, it's free!
it can easily support 50+ people, and has tons of parking (but... it is on a very short dirt road... but it's smooth and generally dust free).
here's a link to the map... it's where westacres drive ends at the point....

so what do we think?
