i started skating about 6-7 years ago. dont do it much atm but ive still got my board… that remins me i need a new one!

i got the basics down like kickflips and heelflips then went on to nollieflips, 360 flips, switch flips, FS flips. the best i did was BS 180 and boardslide a six stair.
snowboarding is kind of similar to skateboarding in terms of the way you stand and the balance but the feel of it and the totally different terrain make them completely different. but one things for sure if you start either it will be easier to pick up on the other.
first things first are you right footed or left footed? if youre right you are regular stance which is left leg forward. if youre a leftie you are goofie stance which its right leg forward. although if your weird like me and your favour a stance which is the opposite to your handiness go with it. im right footed and skate goofie.
the best way to start is to go out and buy a cheap complete setup make sure its already put together or better yet borrow a friends board and start rolling around and learn to balance and try and learn to ollie. you dont need pads or skate shoes just a board and concrete and a desire to learn!
once you learn to ollie and you got your balance down buy a board, trucks, set of wheels, set of bearings and make a setup which you can afford. the skate shop will put it together for you. then buy some durable comfy skate shoes and your set.
the rest is up to to you! get some buddies and go to a skatepark or do a street session. in a year you would have learnt the basic flip and grind/slide tricks. after that comes your creativity, mastering the basics or learning harder tricks.
tip: best way to learn the names of tricks and frontside, backside etc was to play Tony Hawks. man is that game ever addictive! the names just stick in your head after playing.
