I'm right in Medford and a frequent attendee of the Back Alley bottlle shares where I learn more and more every month from enthusiastic homebrewers (plus drink all their beers mwahaha). I recomend that any and every hombrewer in the general area get there on the last tuesday of every month! Also another great place for equipment is Arbor Wine and Beer Making in Islip if you aren't able to make it to Northport
