Paint In The Park!

Hello! My name is Chelsie York. I have a big idea and I need a little help! I would like to start a community and possible area wide event. It is very similar to Geocaching. You collect a rock. You paint the rock with a positive or family friendly message. You affix a premade tag to the back, directing you to the Facebook Page, Southern Indiana Rocks. Then you seal your rock and hide it in our community for people to find. When they find the rock, they can head to the page, log the rock, upload pictures and post clues to where their own rocks are hidden. 
     I think this is a GREAT way to encourage excersize, creativity and family time. 
    What I would like to do is host an event at Shields Park in Seymour as a kickoff to get rocks out there. I have contacted a local quarry for rock donations. People from the are could gather, meet, paint rocks and then hide them. I feel like this is a great way to kick off a great movement.
     What I need is donations to purchase supplies. I would need to get paint, brushes, shellack, modgepodge and to print tags and possibly snacks for participants. I'm very excited about this and I would really appreciate your help! I would like to organize this event at the end of April or the first of May. Thank you so much! SoInRocks has teamed up with United Way and will have a booth at the Seymour Lawn and patio show!
