I gotta say the money has kept me away from the sport for 4 years before buying my first 503. I don't only mean buying the machine only but then you need a rig to carry it, gas in car & Hawk... plus all the equipment, 1000$ of spare dollars in your account just in case something breaks... Ideally a garage to work on it... Tell me a 15-17 year old can afford that... Unless daddy is there to take the Credit card out when needed.. Don't get me wrong here, I wish my father did that... !!! Plus you can be sure that none of their friends have the same hobby, which might also screw up the scale. Plus it's a winter thing you can only do 3 real months a year... If all you budget goes in there, what do you do the other 9...
Instead the kids probably ride skateboard, for 170$ you get a complete skateboard and you can do 1/2 of the summer then they buy a 2nd cheap deck for 45.99$ for the rest of the summer and hold on to their noisy bearings. With 170$ when you go Snow-Hawking, you basically cover the cost of one day of riding with a hotel room shared between 2 guys... That's if you don't blow a 100$ belt or a 220$ cog belt during the day...
My thoughts, no question why no kids are riding sleds/hawks. Lot of kid I meet are all a lot more open minded to the snow-hawk idea than all-time sledders...
