OK, I checked with the school, and yes, they did it last year and it was legit, but decided not to do it this year, so no need to send me anymore. Clinton, who did you say these people were that buy them?? (Other than my local reclclers.....grin) I don't really have a LOT, but hate to just dump them, and I'm going to keep pulling mine off because I find it easier to drink out of the can that way.
