I originally skated, and I sucked. I bought way too many expensive parts that I never used and ended up giving them away. When I moved from rural New York (no skateparks, no scooters at all) to North Carolina, I met a couple middle schoolers who were riding Old As at the time with bolted Razor bars with pipe for the cross tube. I started borrowing them from them (one was a skater previously, so he was fine with switching off for my deck occasionally), and I was hooked. It was so much easier than skating, and a lot more fun and secure feeling. I wanted to learn to bike, but parts were so expensive that I just couldn't. Scootering was a better outlet for my desire to learn and participate in some action sport. I managed to pull together a Franken-A out of friends' spare parts (Old A deck, drilled out dropouts to fit a Pro brake, Pro wheels, Pro Headtube and bars, JD Bug Old-A style fork) and rode that for almost 6 months. It was shitty, I hated how it rode my size 12 foot, 5' 10" frame, but it was mine, and I rode it every day. From there, I bought a RUPv2 when they first came out, just over a year and a half ago, and rode that completely stock with cut bars for 6 months. Then I got a headset for Christmas. Then in June, I traded my friend the RUP bars for a set of RAD OGs. For my birthday in August, new forks and wheels and ICS. For Christmas this year, an SCS. I still have the RUP deck, its on its last legs, but its mine. The whole scooter is mine, I can ride it wherever and whenever I want. I can ride any spots around us, whether biker-sized gaps and drops, or tiny skater grind ledges. It combines the best of both worlds, gives you the freedom to do anything. You meet great people and are able to get involved with an amazing, supporting community, all while enjoying yourself and not giving a fuck about what everyone else thinks.
TL;DR: Ride anything, anywhere. Make friends, disregard haters. Have fun.
