I had a modified radical neck dissection, and radiation for cancer, and now I have neck issues, radiation damage and really bad peripheral neuropathy. My arms and hands hurt and are numb and feel like they are asleep, 24/7. Last year, I decided to try Space Mt again, after not riding it since 2001. I was hurting. I thought it was super rough. Not to mention I am so weak, that I was almost not able to get myself out of the ride when it stopped. I really wish there was someone there to help me, I almost didn't get out. Also, BTM was afoul. Used to be a fav of mine. It was too rough, and I'm so tiny, I just flew all over the seat and got bruised up. Might have been better if I was able to ride with someone else and not alone. Don't think I'll be doing either of them this year.
