So the other ideas were too far away?
If you aren't leaving New Jersey, then try out some nearby sites. You could try this short list of notable NJ landscapes which includes Pier A, Grounds for Sculpture, Van Vorst Park and the Appalachian Trail. Or you could try out our new Rutgers/NJASLA NJ LA Sites Database to explore some landscape sites - it includes NJASLA design award winners like the Smithville Floating Walkway and the Turtleback Zoo.
You could head into Philly and explore Fairmount Park and the Patrick Dougherty sculptures at Morris Arboretum or you could take a train to New York and see his masterpiece at Prospect Park.
Then again, you could just pick up a book.
