I've had only one venture into something like this, and it wasn't really worth it...much better to go with a bunch of folks you know (DEE TEE!), or save up and go in with a few friends on a claimer...I just started my own partnership and claimed my first one today
(Tampa R2 - Wicked Sweet) with a couple of friends...We're all on cloud 9 - she came out of the race in great order, and think with a pedicure (she lost a shoe in the race and has another about ready to fall off!) and a few pounds on 'er she'll be ready to mow 'em down again! Great times...
