I figured it looked like it wasn't about to rain, so I could get my bike home today without getting wet.
I got about 1 mile, and... boy did it come down! I was near a subway station so I hopped on the subway (it was just late enough that they allow bikes) and when I got out, it looked so innocent and dry, like it never rained.

I think I am forced to shelf my bike for the next 7 days until the weather becomes nice again. Grrr.
I'd take out my rust-bike and attempt to ride that down to work, except without a rear brake (tire wobbles too much and needs replacing for the last 3 years), I'm not sure it's safe for a long commute.
Maybe I ought to get that tire...
