Space invaders are attacking the solar system. While orbiting your starship around the Sun, you intercept a taunting message from the invaders. Also, you receive a message from Earth Command. "You are the only one close enough to stop the invaders. Pursue them to the planet Mercury."
Complete the adventure using intercaching, a Web utility that allows your phone to interact with you and your location. You need a smartphone, Android or IOS, with a Web browser and with the GPS turned on.
You can verify your phone works by going to this link and selecting Test Device.

After an introduction, same as the one above, follow the Web GPS to Stage 1, same as the posted coordinates. You follow a limited part of a scale model of the solar system, four stages, seven tenths of a mile. The planets appear at their relative size and relative distances from the Sun (the Riverfront Museum).
Clear a stage by standing at the location and answering a simple question from information in a planet display. The final is a medium container with trading items.
Enjoy caching on the riverwalk.
