Hi Michael, you should try arboretums like Planting Fields Arboretum on Long Island. If not, they might be able to point you in the right direction.
P.S. that gym class of yours seems pretty intensive, making you run on the track. lol

We must not buy their fruits:
Who knows upon what soil they fed
Their hungry thirsty roots?"
