Quiz Friday! Here is our selfie from Seminole Canyons State Park in Texas. We’re not the only ones who had the urge to leave some traces for memory in this park. Question: besides the nature, what is this park famous for?

The winner will get a personal kilometer as well as a place in our Hall of Fame (http://on.fb.me/1JAdFTC). The quiz ends on Monday (00:00 GMT). The winner will be announced on Tuesday(ish). The winner will be drawn at random from all the correct entries.
