[python] Re: Trail

There are two major things happening, and I guess they sort of go
simultaneously.
1)  You use your body/feet/hips/legs/shoulders/whatever to bend the python,
hopefully to an angle that will get you around the corner you're riding
through.
2)  You lean in, and hold your body in an arch in an attempt to balance the
bike at the current speed so it doesn't fall over to the outside.  This is
like doing a track stand on an unpright, but you're moving.

This might seem basically common sense, but the process is just about
opposite of what a normal bike is.  For Marcel and myself, we have to "hold"
the body pose through the corner, you can't seem to realax and swoop through
it feeling "neutral" like an upright bike can.  It's like you counter steer
to start into the corner - same as an upright, but then you hold it.  I was
never very smooth on the corners - thay always had a sort of hexagon shape
to them that was due to my semi-spastic body control.  The speed I was
usually carrying into the corners likely didn't help either.  After the
corner, you let the bike drop back down to center while you lean slightly
outwards so you don't fall into the corner, or you can be brave and sort of
"kick" a little oversteer and snap you up straight.  This maneuver, while
exhilirating, often ended badly :)
