The morning was a bit warmer than I thoughtit was going to be, so had to stop several times to disrobe pieces. On the way home got caught in a pretty good rain the last half hour or so. It really wasn't too bad once I accepted that it was going to be a very wet ride. But I was quite chilled by the time I got home.

Bike seats... From my experience it could be several things.
- just getting the rear end used to sitting on the seat for distance.
- could be the seat needs adjusting, angle etc.
- bike shorts can make a significant difference.
- perhaps a different seat is called for.
Folks at your lbs should be able to help you out with this. Good Luck.
