Not sure where this is but I am in the "Rogue/ Applegate Valley" area in Oregon and THIS is what we see on the regular this time of year. The afternoon winds here can be insane so people just launch and go for it. I heard the other day one dude made it something like forty miles up the I-5 corridor a few weeks back, though there are always rumors of such feats!
I would like to try it but am so damn scared. Sometimes there are groups of dozens of fliers that jump together; pretty kewl thing to see. Thanks for the share and have a great day!
