Brilliant.

Here’s how it works: You decide on the amount you would like to pledge for each
protester (minimum 10 cents). When protesters show up on our sidewalks, Planned
Parenthood Southeastern Pennsylvania will count and record their number each day from October 1 through November 30, 2005. We will place a signoutside the health center that tracks pledges and makes protesters fully aware that their actions are benefiting PPSP. At the end of the two-month campaign, we will send you an update on protest activities and a pledge reminder.

Example:
If you pledge 30 cents per protester, and PPSP has 100 protesters in October and 160
protesters in November, your donation would be 78 dollars for the entire two-month campaign.
