dude. you can't build a snowman out of rain. rain's no fun. snow can be no fun as well, but there are ways to have fun with snow that don't exist for rain...you just can't do some things.
but get used to rain, if you must. i've gotten used to riding bikes in all weather. when i lived in boise i rode in weather that was in the single digits (8 degrees, for example) many times. sucked at first, but i got used to it. summer heat....got used to that. boise also gets well above 100 degrees in the summer (when i moved back, for example).
