Charlie,
    I'll probably take you up on it when I get some time but the demands of
running one business, starting another in a down economy, and having a
teenager and a 2 year old with boundless energy sure chews up my
free/tractor time! This IS one of the pet projects I want to experiment with
in the next couple years, after I get all my tractors running properly...
just don't have the "round tuits" that you seem to have. :)

Thanks!

Ken in AZ
