He's been diagnosed for about 8 years now so we have gotten over the "shock" of it. He even has fun saying it gives him great parking. We're not happy about it but what can we do, other than fight for better drugs and research. He could do Mantis, he's able to walk still, just not very well and a long day in the parks requires his scooter. By the way, his disease is one reason he loves coasters, they allow him to be like everyone else for a few minutes. That's why I buy platinum passes and Ace memberships for Christmas.
