Common household remedies request

For a Corrente mapping project I'm -- touch wood -- coming down the homestretch on, I'd really like map icons that represent political actions; for example, Dan's meeting with local officials might be represented by a gavel, a march by a sign or people marching, etc., for many forms of (non-violent) action. For example, we have Green Map Icons for bike trails and farmers markets and so forth, but I'm looking for icons in the (non-violent) political sphere. Readers?

Because they will cluster on a map, the icons need to be small and single color; not Web 2.0 lozenge-y gradient-y candy-ass buttons, but simple and clear icons.
