You try to remember where you've seen Josh before. Maybe it was setting up a line at Queensbridge Park or hanging out at Brooklyn Boulders. Or maybe it was when you were watching the GoPro Mountain Games or World Slackline Championships as he was soaring and twisting above a slackline. You see, Josh is no normal Brooklyner - though there may be no such a thing as a normal Brooklyner - he's also a former competitive slackline athlete.

See it to believe it:

Now a rock climbing instructor at Brooklyn Boulders, Greenwood loves getting people excited about the outdoors and the fun of slackline. In that vein, he'll be teaching both beginner and advanced slacklining clinics at the OutdoorFest Campout next weekend! And if you can't make it to the campout, just head over to BKB for a rock climbing lesson and a few slacklining tips from Josh.
