Yeah, it was very hard to resist the temptation of getting in there and mapping all the fields and figuring out which school was which and the like, but I've decided I have to focus up.  My goal is ensuring every publicly accessible street and trail is correctly mapped and tagged, and I'm gonna have to leave some non-accessible stuff for others.  I've got a long list of parks to get through and here's hoping I won't be unemployed and able to put in 8 hour days of mapping for much longer!

Good to know about the more general tag - anything that communicates "hey this open green space is not a park" does the trick for me!
