Accom for Sat night

Hello
We are 3 Australian's and one American looking for some accom for Sat night (ideally tonight too but we arn't getting in until around 3.00am), we are climbjng at the Gunks for a week and have booked into the campsite from Sunday onwards but it was booked out over the weekend. We have sleeping gear and tents, just wanting to know if there was free camping close by where we can stay/find easily at night.

Thanks for the help

Hugh
