Another Seattlite chiming in -
Gear makes all the difference. I also have an Aerostitch Roadcrafter (great suit, but certainly not the only good choice), and don't give a whit if it's raining or not. However we don't get the pounding rains that the gulf states get. In those conditions only a true rain suit could keep you dry.
The limiting factor for me is temperature. An electric vest is a great equalizer for the chillier days.
Powerlet makes nice quality BMW-style sockets for adding accessory power to your bike. I've already got one on my Valk, and will receive their Sportbike II socket in the next few days for my '04 S3.
When the frost comes out, so do the car keys :razz:
