make SURE you get your binds adjusted no matter how many times you adjust them, i board with a 3-3 duck(3, -3 maybe?) and love it.
also just get comfortable staying on your heels first instead of toes. watch out for ice, cant get any edge with ice and it hurts

take your back foot out when getting on and off lifts to give you balance in case you start to stumble.
always fall backwards if possible and dont be afraid to fall if you pick up too much speed.
if avail. TAKE lessons for a few hours, i did my first day and it helped alot. i could go on my heels fine but it sucked because i had to pretty much stop to get going the other way, i finally picked up how to switch from my heels to my toes without falling and since then i can fly down mountains. ive only been boarding twice in new mexico and LOVE IT(going this year too) i can hold my own too, gonna learn the rails this year.(of course i wakeboard very good but its on water, it still gives you a little advantage and i used to skateboard ALOT).
if trying to switch from your heels to your toes, just kinda of turn your body backwards and kick your back foot behind you and it will throw you and your board from your heels to your toes, sounds hard but it works.
dont land on your back and let your wrists catch you, they will hurt BAD at the end of the day. just kinda cross your arms and drop back and roll back kinda(arch your body so it kinda rolls)
also watch out for dry spots(mud, dirt, grass, etc.) i went boarding last year in march and it was mostly manmade so when i saw a patch of dirt i went over it and came to a complete stop, it sucked. now i love seeing the dry spots so i can jump them
i love snowboarding more than anything on the earth(even fapping) but it sucks cause i live in arkansas and can only go once or twice a year for 4 or 5 days at a time

hopefully i can move to the mountains one day. if i grew up around snow, bet money i would become pro.
kinda typed too much, sorry but i love boarding so much
gl and report back with pics!!!! also if you know what manualing it on a skateboard, its twice as easy to do it on a snowboard, just lean back all the way and pick you front foot up, lots of fun if you can balance it.
