Greenfield & US 60, there's a Quiktrip 1 block south of US 60, on the east side of Greenfield. There's a Starbuck's right next door.
Meet up at the Quiktrip at 7:00, depart 7:30.
Route will be east on US60; south at Florence Junction on 79/77 to Tucson; east on I-10 (from 77/Miracle Mile); exit Valencia; east to the museum.
Think that should get us to the museum between 9:30 and 10:00 AM - for meeting up with anyone coming by alternate route or any Tucson peeps that want to join.
