The CT DEP has quite a bit of unrestricted data available on their web site; I've been working on getting the boundaries for the state parks uploaded. Been going slow trying not to stomp on anyone else's edits or make a mess of things; I think I'm about halfway through.

See here for the source data and usage policy: http://www.ct.gov/dep/cwp/view.asp?a=2698&q=322898&depNav_GID=1707

Will post an update with the guidance I was using to tag these features.
