I'm slightly curious myself. I'm assuming a friend on a nearby bike with a gopro on pole? Atleast I hope its on a pole, otherwise idk if i wanna ride with you guys keeping that close! haha.
Always intrigued with new angles as i majored in photography in college. Thanks for the different perspective!
Also, if there are 2 bikes, wheres his bike when ya'll are looking down out of the tower?
