didn't this already change for Minnesota, or is April 1st also the deadline
here?
Apparently, as of April 1, 2002 there is a new valve
arrangement on
propane tanks. See the link below for all the details.
Older style tanks,( of which I have many) will not be re-filled. I am
going to re-fill my tanks this weekend.
