John Jackson has finished his trip on his Catrike Expedition in Centralia, Illinois.

He started in Sacramento on March 7. We had a lot of fun wrapping up loose ends with him.

Check John's blog.

Once again, we had the opportunity to turn out in support of Kyle Bryant and his band of amazing people.

350 riders rode whichever ride worked best for them: 60, 40, 10, 5, or 1 to raise funds for research to cure FA.

An incredible $110,000 was raised as well as the hopes of all.

I was looking for the next thing for my rehab... and, this is it! --Rocky

Planning Hiawatha Trail for mid August!
