I am completely impressed by those of you who commute in any kind of inclement weather.

It was drizzly/misty when I rode in today and not only were the roads treacherous but the drivers were bonkers and I kept slipping off of my handlebar grips. I had to take my goggles off because I couldn't see through the wet but many of the other riders I saw were still wearing theirs. So now I have several questions:

1) How do I keep my goggles see-through in the rain? (Or do they just need to come off?)

2) What can I change on my handlebars to make them more grippy when wet? (They are currently a smooth leather decorative grip, not tape.)

3) Are there tires that are more stable in wet weather but also work for dry weather? (It's dry here 90% of the time.)

Do you have any other tips for riding when it's wet?

Thanks a bunch!
