This seems to be a controversial topic here.  Nearly everything I've seen
elsewhere on the topic has said that for fairly small quantities (like the
contents of a Vanagon cooling system) it's okay to pour it into the
sanitary sewer and flush it with fresh water. (i.e., down your toilet or
sink, but *not* into a storm drain, please!)  Apparently the sewage
treatment plant can deal with it in small quantities.  This is probably
not a good idea if you have a septic tank.

You can check with your local recycle center or hazardous waste drop
first, though, some of them may take it.  Last time I did a coolant change
I wasn't in an area that had one.
