I found this sequence of Gareth that hadn't been used for anything so I figured what better way than to post a instructional trick tip. These are my words not his. I'm just using him as my stunt dummy.
Step 1: Climb onto the highest possible structure you can. Hopefully it's high enough where you can't even see the bottom where you're supposed to land.
Step 2: Get in tail drop posistion or dump truck or nosepick or handstand or criss cross applesauce or whatever you feel comfortable jumping from onto a skateboard.
Step 3: This is actually part of step 2 but it's so important that I'm highlighting it and including it in it's own step. Point to your friend at the bottom and say "this is for chicks" or "get money" or "pirate life" or "gangster life" or whatever you feel comfortable getting into at that moment in time.
Step 4: Go for it.
Step 5: Don't think about falling. Think about landing. Think happy thoughts...
Step 6: Be very thankful that you didn't completely mess this up! Suck up the impact and party down onto safe grounds to celebrate.
Step 7: Make sure all your friends filmed it. Go straight home and edit it to a sweet song and send it in for sponsorship opportunities.
