Hey Robyn,
Sorry you don't feel well. I've had the same problem this week. Think I'm fighting a bug off, but just feel run down. Opted out of a ride with hubby yesterday and today so he took my son.

Have you thought about just putting slicks on one of the mountain bikes for a few weeks till the roads are cleaned up? Probably the hardtail would be best.
My Surly tank is great because its a cross bike I can put fat tires on and ride the dirt and then skinnies when I ride the road. I pay on the hills because its heavy but I need the workout anyway.

Feel better, we hit the 50's this week I hear.
