Wishing you the best.
Segway i2 has changed my life. I have had it for 3+ years.
I also have MS. Fight the good fight!
I have swapped out factory tires for UrbanMaster (
http://www.segwayofcentralflorida.com/UrbanMaster.php), the tread is outstanding on trails. I have taken Amtrak, even an air flight.
