Planetary Rings

If you don't know where you are on Earth, the angle of satellite dishes can help constrain your latitude. If some of them are pointing straight up, you're probably near the Equator, right under the ring.

I understand it's hard to do more than 300 feet on these 90-second rush jobs, but with a smaller ramp I'm worried the gee forces will be too high for me to do any tricks.
