Hi ya.
Mt boarding is like snowboarding only without the snow.
Mt boards have both slip in and out bindings, as well as Snowboard style bindings.
The good thing is that they have Breaks.
It's about 46 to 48 inches long with a 14 inch width.
Andrew the best Mt board retailer in the world is near you. MBS mountian boards is located in Colo Springs.
This is their site :
MBS MOUNTAINBOARDS
I would also say get Body Armor w/spine protector (Pressure Suit) Gloves, and a closed face helmet.
****You don't want an open face helmet as for your feet are in bindings and you will fall on your face or back/ass.****
I also recomend Impact shorts too! You can find those in snowboarding gear.
All of the above mentioned gear can also be purchased on eBay as well. I get killer deals there.
A total Mountian Boarding setup will run you around 500.00 or more.
My board ran me 600.00 alone. My armor ran me around 300.00 for it all ( helmet, pressure suit, gloves and Impact shorts)
But once you buy the gear that's it no more cost.
Except for the occasional trip to the hospital. LOL
BTW Andrew I recomend the ski slopes in the summer to board on, and also try out the enchanted forest too.
