Given your philosophy you should be riding a Surly Pugsley!...

Ah yes, the Pugsley. I dreamed about one all winter last year. The thing with the LHT is that it's my do-everything bike. So if spending thirty bucks on tires gets me a bike that can take me through the winter
well enough, than for me it's a better option than a new bike. I can put that money towards the next tour.
That being said, I would really love a pugsley...
I should note that my winters are spent in Rochester, NY, where we get plenty of snow, and not in San Jose...
