I'm a 62 years old Dutchman and in the Tucson area in April. Much biking on the road in Europe, but in the States I'm 'blank'.
About 6 April maybe. After 10/4 I'll head for Albuquerque (via Grand Canyon) by Greyhound/bike (where nd when possible).
About 50 mies a day??
If that's your cup of tea, please mail.
