Hello Dr. Res, et al,

The plan is to take the menagerie to HS football stadiums to interest young
people in science near the Southern West Coast. I have a ways to go to be
ready for that and need a 1 million dollar liability insurance rider which
may be hard to get!

Sounds like an interesting demo.  Where do you plan on doing them??
