Keep my bike?

[Crankin]

You know, I felt like that almost the whole time I had my mountain bike. It was a nice FS bike, but I don't think I ever rode more than 7 miles on it. I had one, maybe two seasons where I improved my skills, but since I was always riding my road bike, it stayed in the bike shed most of the time. I ended up walking a lot. My fear kept me from really enjoying the experience,despite the fact, I love being out in the woods.
We used the bikes once last summer on hilly dirt roads in Maine and even that bothered me. It just feels so different than road riding, and after that I was OK with selling the bike. Funny, even though I can do 50-100 mile road rides, I just never "got" the mountain biking, despite really wanting to be a tough dirt girl. The most humiliating riding experience I have ever had was a group mtb ride on the "easy" trails at Great Brook Farm and the Cranberry Bogs in Carlisle.
I would sell the mountain bike, keep riding the Sirrus and after awhile, if you do get a road bike, keep the Sirrus for errands or commuting.
ETA: I did start road riding on a hard tail mountain bike, with slicks. It's aluminum, though, so not really heavy. It was DH's first mountain bike and eventually I used it for an errand bike and it was then given to my son, who used it to commute in the city until he bought a single speed.
