from my limited experience wooden rails slide ok as long as they are'nt the kind that are just an unfinished log. dont bother with sanding, its a waste of time, a lil wax never hurts, and if all you have to work with is a parking lot i would go with a good ole bumper push, as long as you have enough snow for an inrun
put vid on NS, haha
For your first question, i think you should hit it at night, because if its open 7 days a week you would need to wait up for a holyday or something.. plus. night sesh's are fucking sick.
for your second question. it really depends on how steep/how hard the rail is to get on. i'd suggest if you have legit parts to make an in-run you should go for it because u dont need that much snow for it
lastly i think you should put some sort of wax on it, i dont think skis would slide on wood like that
hope that helped. im just saying what i would do,
I have hit 3 or 4 wooden rails before heres some tips....1. make sure its dry becuase wet wood chips alot easyer. 2. make sure there is no large splinters sticking out and if there are peel them off so nothing is sticking out. I will say splinters like that dont matter as much as long as they are pointing down the rail. Lastly Run your skis down the rail a few times putting a lot of presure on the skis to make sure there is nothing ready to chip that could chip while your hitting the rail.
Thats it and make sure your edges are well rounded.
oh also if you do wax its best to let it set u also found this out after my last post. it will slide fine even if you dont. but if you do its actually very nice
