Vanderbilt Mansion and outdoor pics

Funny you should ask, I just called about that yesterday. They basically give you an hour before your invitation to use the facility. I'm going to find out if I can get there earlier and use the back lawn on the river. I think I need to call Dowling College to find out since its just part of there campus.
When I went to college anyone could just get on the grounds, so I don't see why this wouldn't be the same case, as long as you don't mind so random students possibly being out there till that 1 cut off point when then get kicked off the premises.
