important note:
when hitting a street set up, you wanna make sure to get your uphill foot above the rail before your downhill foot. that is, if you slide right foot forward, pop, get your left foot over the rail first, then worry about the right foot. this is because of the way the rail is slanted downhill, you will have to make your uphill foot move more, while your downhill foot has a bit more time, since it will land further down the rail, and due to the slant, at a lower position on the rail.
hope that made some sense haha...
