A friend and I (let's call him, say, Lance, but not THE Lance, if you know what I mean) spent the day riding our bikes up and down Hyalite canyon south of Bozeman. The idea was to raise money for Eagle Mount and their Camp Braveheart program.
Lance made six laps before his right knee blew up.
I made eight laps, for 128 miles, in 10-1/2 hours of riding.
Not too shabby. And we raised $2k for Eagle Mount.
