I don't have a dog in this fight, but...

1 - What is the motivation behind the bill? Are they searching for additional sources of tax revenue? If so, can you offer other options?

2 - What are the actual chances of passage of this bill? If it's unlikely to pass, why do anything? If it might pass, are there political avenues that can be taken such as calling in a favor from a well-situated political friend?

3 - Are you being baited into over-reacting? If the Councilmember sees this as a longshot, she might be clever enough to get you to prove her point for her by getting you into the streets. Then she can step in front of a TV camera and tell the good folks at home that bicycle licensing will put an end to all this out-of-control revelry.

I know I'm just a simple southerner who doesn't understand life in the big city, but redneck South Carolina sheriffs have been using that last trick it for ages. And it still works!
