所有地理藏宝平台的开源项目跟踪
A wooden Coin, planning to travel to many beautiful Opencaches. Can you help her? Let's see how far she can come! The shape is (although its not a circle) of constant width! (and fits in a film canister) Its called a Reuleaux Triangle - look it up! Have fun geocaching! PS: you are very welcome to log with a picture! :)
