I did something similar to Allezgirl. I wrote a letter using the examples from our local chapter as a guide. I made it personal by adding some quick snippets about some of the people I've met with MS in our fundraising efforts.

I then sent it to everyone on our wedding guest list! Then I called my mom and asked her for some names...and I sent a slightly different letter to her friends (ones where I added my maiden name so that they'd know who I was).

I raised over $2300 and the vast bulk of that was from these letters.

I'm in the process of putting together the thank you letter with a story about the ride, photos and a reminder that we plan to do the same ride next year as well.

Next year, we will expand this to a door-to-door effort in our neighborhood. Oh, and asking local businesses is also good.
