Just got back froma few days up north. I dragged my MTB with me and rode there every day. I live in a fairly hilly area but the hills up there were BRUTAL! No ride was longer than six miles or so. I almost got adaopted by a dog who thought running along with me was great fun! Still, I was pleased with my performance and am really starting to bond with my bike. I have several bikes actually, but this Sorrento is the one that I have had the longest and the one that I ride most. I am getting quite fond of it actually.
