Imagine: You propel yourself down the board walk, banging your head to your iPod while trying to keep your balance. Your eyes are closed, the sun was hurting your eyes. It doesn't seem like long before you feel your skateboard hit a bump, and you feel yourself falling. Luckily,someone, also on a board, catches you. "Careful, there. You might want to keep your eyes open." You stand up, brushing yourself off. "I will, thanks." You grab your board, skating off. It's the first of many encounters.TBC
