Your in Bridgewater... so ur not that far of a drive from my area. See if you can set something up with Waterloo Village, cuz Im sure they arent holding any field trips, especially since there is no elementary school in the summer. Also, the ITC Trade Zone in Mt. Olive (right off Exit 26 on Rt. 80W) has a ****load of parking lots and alot of buildings with mirrored windows. Or if you wanna make a little extra trip, refer to this thread where I took my last pictures
