I will be dropping in and posting some teasers over the next couple of days, while I continue to process the entire race gallery (ie. while I try to NOT crash my computer, like last year... ahem). It was great to see all of you out there in that glorious spring (?) weather! Enjoy the teasers and I will post a big announcement once the entire gallery goes live...
