Living in the "middle" I'm not sure which way I would go, east or west, but I really enjoyed LotO last year because it was all Spridgets. I get tired of being the "red headed stepchild" at the MG as well as Healey events, it was nice to have an event all of our own for once. Because of that I would more likely drive farther to attend an all Spridget event than I would to attend an existing event where Spridgets are the featured Marque, I can do that right here in KC.
I met a lot of new friends at LotO, mostly from the east or southeast, so that would play a major factor in my decision, but I'd like to go west just to be able to visit with the fine folks out that way as well. It's just that Nevada in June sounds a bit warm and the Midget is a pretty warm car to travel in at any time other than the dead of winter.
I know that's of little help in choosing a site, just try to make it an all Spridget event anywhere and I'd be more pleased.
