well u could learn a feeble grid which can double up as a feeble
stall but it takes a lota practice but once u get it down its a neat
trick

what u need is some sort of low rail or a waxed curb (the curb is
easyer)
then ride up slow, parralell to the curb and hop on.

when u land what u have to do is keep your front wheel on the
pavement but leave your rear wheel hanging over the road.

BUT...
u MUST keep the front wheel pointing the same way as the curb other
wise you wont slide along youll just stop or fall off.

if u keep the wheel parralel with the curb just slide along untill u
want to hop off or run out of speed :)

if u decide to grind the rail ride up at a slow but fair pace and
hop on
but this time u wont have your front wheel to help keep balance so u
need to keep your body weight ontop ov the part of deck thats
slideing on the rail .

i find standing at the back of the deck near the brake and sliding
under your feet is the easyest way on a rail but experiment for
yourself.

hope this helped o and allways where your pads and helmet :P
