So I just completed my first week of commuting (omg, love ). Wow, I wish I had a t-shirt that says "use your turn signal"

Anyway, I have been fortunate enough to have very fair weather so far. I'm concerned about the rainy weather though since I don't have disc brakes.... I have ridden in the rain before but never more than 1 mile and on busier streets, and general find them to be undesirably slippery. Any tips/advice about using my caliper brakes or needing disc brakes in rain?

Thanks!!
