It's looking like (but it's not completely settled just yet) I'll be in town for the HP extravaganza.
While fully realizing that accommodating everybody is impossible...I'd suggest the Copper Triangle on teh 20th. That way I can race on the 19th and join you on the 20th.
Also, the Omnium the following weekend starts with a TT on the 24th wherein a certain modern Beryl Burton could teach these Colorado wahoos a thing or two...
