Rode in today. Took the rock hopper with the studded tires just in case. The streets were mostly clear with maybe three instances of gutter to gutter ice. I had pumped the tires up to their dry setting. 65 PSI actually 70 and the bike rode very nicely and very quickly with very little rolling resistance for these tires. I rode over the first two ice sheets which were a little lumpy and the bike slipped a little bit over the lumps. I know that if I had lowered the pressure it would have been flawless and secure, but the rest of the ride would have required more effort. The third ice field was on a steep downhill and I decided to get off and walk for the half block.

There were plenty of ice patches but all were avoidable except for these three.

I have an eye exam tomorrow morning before work and I am considering biking there as it is not too too far off one of the trails. I thought about biking but it is not a secure location for a bike to be locked up in my opinion .I think I might take the small folder which now has a quick release back rack and everything fits inside the carrying bag. I'll see how I feel about it in the morning.
