Plastic bag recycling

[jbdowse.livejournal.com]

I Googled around, and searched davis_square's archives specifically, and didn't find anything about this. Is there anywhere in the vicinity - Medford/Somerville/Cambridge, or maybe further afield - where I can recycle plastic bags (i.e. regular shopping bags & other #4-plastic bags)? Does Shaw's or another supermarket have a return? I've got a whole trash bag full of them, accumulated by my roommates and me over the course of the year, and I'm moving out Sunday, so any help is highly appreciated. Thanks! (or if you can use a whole bunch of LDPE, let me know!)
