We're gonna miss ya! I wish you didn't have to sell the Blaster, but just remember you're young and will have plenty more chances at getting ahold of another quad to ride. Don't give up!
Just FYI, I personally didn't even set ass onto my first ATV until I turned 18. My dad forbade me from having any "motorized" 2 wheelers or ATV's period as a teenager. So you're already way ahead of me in experience and enjoyment of your teenage years. I spent most of my Sophomore and Junior years of high school depressed and hating my life. I don't remember some of the days. I just didn't care anymore.
BUT, at 22 years old now, I can tell you firsthand how much better life will get. I soon got to ride again (my uncle let me on his Honda Foreman once when I was 14), and got a promotion at work. Now Im happily married, own a house, and still managing to enjoy the Blaster. It is not easy and money is tight, but my wife is on my side...she helped with the Blaster build...and we can get through anything.
You'll get another chance! I promise. I had to sell my Banshee two years ago and I thought my life as I knew it was over. But, after 8 months I bought a TRX 450r and had my Blaster built, and I was back at it!
Save your $$ (it really works!), get that truck, work hard, and there ya go!
