ive recently started locking.
The first place i looked was here but theres very little on locking.
I rememberd learning about locking from this sick bboy a while back. All i can remember was this thing he showed me where you like roll your wrist up and down and shit. So with that knowlege i went in search of locking guides and vidoes. There was shit all guides but i found some nice videos. Them i came along a sick ass forum with some sick ass lockers. No shit these guys have got skill. There are videos and shit there as well

So now ive got some basic locking down. It is as alot of you have said you just point at shit. Watch the videos you will probably get a few ideas.
Remember though dont bite watch the videos, get the basic feel and idea then create your own locking shit.
