Interesting subject...we just discussed/dealt with this in the beginning of April. How far along in pregnancy should you ride? Should you risk a mountian trip? I'll be honest, I haven't read the article yet, but I will. The warden and I decided to do our annual family trip earlier this month at 3 mons pregnant. She felt comfortable and decided to go for it, but just take it super easy. I did have a scare on one decent when she was fish tailing out of control with her brake locked up, but after that it was a breeze.(I forgot to remind her of the braking procedure down sketcky hills in spring conditions this year) my biggest concern is here sliding into a tree or the machine flipping on her.(she truly is a rookie but gettin better every year) I'm glad to say we had a great weekend and our season is over until next year....baby is due in Oct. Thanks for this Momma.
