dew tour normal has a a open event for each event like this summer they had the Nike 6.0 Bmx Open in chicago in June then a couple weeks ago they had the Skate Open in boston. I know for the BMX Open they had tons people at the quailfers for it. I'm sure winter would be the same way or maybe not.
free flow is pretty simple. win what ever reginol event you chose to compete in. Example one of my friends won BMX Park at 4 seasons skatepark in Milwaukee in june by winning that he is flown out to the TOYOTA CHALLENGE stop next month in Salt Lake, UT to compete with all the other winners in the Free Flow finals for a spot on next years tour.
Pretty simple how it works
