If you live near a YMCA, you can contact them and ask them to start a Pedaling for Parkinson's at the Y program. There is no cost to them and they get researched protocols for the exercise, measurements for both physical and cognitive responses on their participants, and become part of a community of people making a huge difference in the lives of people with Parkinson's. Since I'm going to Africa shortly to climb Mt. Kilimanjaro with a group of PD and MS patients, I've asked potential donors to donate to the Pedaling for Parkinson's at the Y effort on the pedalingforparkinsons.org webpage. Hopefully, we'll be able to help purchase bikes, provide scholarships and respond to other requests. (I can't believe I'm more fit with PD than I was before I had the disease.)
