OK.. This more of a personal milestone, but I thought it was worth mentioning.

Noticed this when I got home from July 4th ride out in the Hill Country.
Thumper has "lapped" Mad Hamish in the odometer arena.
Mad Hamish 37,996 (call it 38,000)

Thumper 138,043 (call it 138, 000)

and I have video of them both running, and both the odometers.
Next milestone target: 150,000 for Thumper or 200,000 combined
