I'm going to give you several ideas using the number "514" as the theme.
If you have some kind of entertainment place such as a movie theater, night club, concert hall, etc. you could charge $5.14 admission on May 14 and donate it to IYN.
If you have a pizza place, you could have a "Buy a large pizza for regular price, and get a second one for $5.14!" offer on that day. Of course, the $5.14 from each special offer would be donated to IYN.
If you do runs and/or other forms of thons (e.g. walk-a-thon, rock-a-thon, dance-a-thon), you could have several people pledge $5.14 to be collected by you if you finish your goal.
How fast might you get various business in your community to donate gift certificates to their businesses? These would go into grab bags which could be bought by people for $5.14
This handful of ideas can be adjusted to go in various other directions. Whatever you do, let's do something creative on Friday, May 14, 2010 that has a 514 theme to it and will raise funds for IYN. If you just so happen to have an address that has 514 in it, you might even consider having a get-together to do something such as knit caps for street youth to wear.
Please share this information with others. . .
An added challenge:
If you're reading this, please do what you can to try to get at least 514 more signatures on each of these petitions by or before May 14, 2010. The number to the right of each link shows the number of signatures at the time that I first issued this challenge:
