Physics of Skateboarding

Okay, so before the hurricane I wan skateboarding and I wondered how I stayed on the board when going through faster and sharper turns. Turns out that there are two sets of forces involved, that of the skateboard on my feet and that of the skateboard to the ground.

When you turn on a skateboard, you need to bank both the board and the body to increase the centripetal acceleration (thus centripital force) of me against the board. But banking too much would lead to too much horizontal force against the board when it is acting on the ground, thus making it slip once it passes the maxiumum force of friciton on the ground.
