NYC area thrift shop vinyl

I just moved to West Point, which is about 35 miles up the Hudson from NYC. Does anyone know where there's any thrift shop vinyl to be had? I've checked a few of the local Goodwills and Salvation Army stores, but none of them had anything. Certainly not like Oregon, where some thrift stores had 1000s of LPs. I've found some good used vinyl stores, but their prices are all in the $5-10 range. Nothing beats the satisfaction of discovering those mint LPs at $.99! :-)

I'm willing to drive a ways if I know I'll find something when I get there, so probably anything within a 50 mile radius of NYC is in bounds, or maybe 100 miles up the Hudson. Thanks in advance to all you east coast Audiogoners!
