15 gal long?

I catch both ringnecks and rough green's when i go upstate New York to my uncles house. Both are very common, shouldnt be a problem to find one... but i still want to catch that copperhead that got away...
 
Idk last summer I didn't even see a garter snake minus well any other kind... my uncle found me my ring neck and i had a albino milk snake baby in my basement besides that nothing.
 
My uncle has like 150+ acres (in his attempt at manifest destiny) about 20 miles south of Binghampton. Last winter, we took a bunch of the old sheets of metal from the roof of some abandoned barn and layed them out next to his shed. By the time spring came we had a "snake garden" as my dad referred to it. The grass under the metal died and decomposed over the winter leaving dirt under them. the perfect place for a snake to heat up in the morning. We caught snakes by the dozens each day.
 
Well I decided to use my old 30 gal tank instead of my 15 gallon... Does this open me up to any other options? snake or lizard... When its fully set up ill post some pictures.
 
That depends if your still going for the "community". If your not, I woud do some sort of king, milk or cornsnake.
