Necessities:
- dress warm (bring extra gloves)
- take food/drinks
- make sure you have shovel/probe/transceiver, and make sure you and the people you are riding with know how to use them (most important)
- take enough fuel (depending where you are riding, don't want to run out of gas)
- take a 2 way radio and/or GPS, it is very easy to get lost in the backcountry (and extra batteries)
- take a rope to use as a tow rope in case you break down
Riding:
- in the pow, use that throttle, otherwise you will get stuck, and after a few stucks you won't want to get stuck again, its alot of work to get out
- stand up all the time, don't sit, you need to be mobile
- use body english to steer the sled, and to turn in the powder always countersteer (to turn left, steer right, and body weight to the left)
- if you plan on climbing any hills, stay on the high side when turning around, laws of gravity will apply and you will roll down the hill
- when descending, try not to use the brake, keep burping the throttle to keep the clutch engaged, the engine will slow you down better than the brake will
Have fun and be safe
