I will take delivery on August 22, 2022!
🚲 Tempe to the South Rim Loop 2024?

The future is beginning to happen. I ordered a custom Co-Motion Pangea, Pinion gearbox, light green with dark green labeling. It may arrive in June 2022!

My previous touring rig was a 1998 Bruce Gordon Rock & Road. I have my eyes open for my next touring rig. A lovely resource for bicycle touring is the Adventure Cycling Organization - member since 1988.

Its now been awhile since I've toured - raising a family. I like to claim that bicycling touring is part of my past and part of my future. I can hardly wait for my next tour - I miss it.

I entertain myself with long distance bicycle adventures. I rode solo between 1986 and 1996. Nearly all the images (and lessons) from those adventures reside only in my synapses. When Jeannine and Frank started to duet in 1997, some images from those trips were recorded:
🚲 Barranca Loop 2004
🚲 North Star Expedition 2001
🚲 Chicago to Toronto Loop 2000
🚲 Tour of Wisconsin's Thumb 1999
🚲 Southwest tour: San Diego to Silver City 1998
🚲 Santa Cruz to San Diego 1997
🚲 Tour of Georgia 1996
🚲 Chicago to Aspen 1995
🚲 Santa Cruz to Aspen 1993
🚲 Santa Cruz to Cabo San Lucas 1991
🚲 Seattle to Santa Cruz 1990
