So I'm going to ask my girlfriend to marry me. Planning on doing a bit of a scavenger hunt through a Christmas lit park. I'll have family members and friends at strategic locations that would give her a coordinate (Probably longitude/latitude) that would eventually lead her to me. So i would like to utilize our droid phone. She's not completely tech savvy, so I need to try to make it as simple as possible. I'm thinking about an app that can have coordinates easily entered and then have a map or compass that guides her to the locations. Anyone know of any app with these abilities? I was looking at Geocaching apps, and I would imagine I could just create some cache's???? Any other bright ideas? THANKS!!
