Since I remember skating as a young child I was amazed by Rodney Mullen. Today he's still skating and is even more impressive than before. Many skaters have suggested that Rodney and Mark Gonzales have created the modern street skating with their mix of technical skills.

Recently I was reading a discussion about MMORPG's on-line games and found this game web site. Second Life is basically like a huge on-line game but where it's different from other games is there are no objectives, instead you just build and explore the world. I tried this game out and was impressed with the amount of game space you can travel.
Like with most on-line games, there is a monthly fee but you can create an account for free and explore the world. The only down side is you can not buy anything (in game money is bought with real world money) and you can not own any land (houses can be built in the game). It's still free and fun.
