Diminishing Enthusiasm.

[Water Warrior 2]

So here I sit at my desk and have a very rideable bike a short distance away. I don't really care anymore about riding. Seems I have hit a real slump in my enthusiasm for riding this year. Beautiful fall weather and colors to enjoy but I keep grabbing the keys to the Ranger.
Having ridden the Vstrom for 5 years now I wonder if it is time for a different ride or just wait till the spring and play with the idea of riding again. Anybody else gone through this lull in interest ?? Maybe the 7 year itch come early or something similar ??
