I keep rcs as well. If you are looking for different types of shrimp in NJ, check out Fishtown USA in Ramsey (Route 17). I was there this past weekend, and he had a LOT of different types of shrimp, some I had never seen or heard. Prices are a smidge high (4 or 5 bucks each), and he will give you a small deal when purchasing a few (forgot the deal). Definitely worth checking out.
