Hey, thanks a lot for the replies, guys! It's definitely not an Arbor, I found those pretty quickly online. I don't know the length, there's a price sticker on the board that says "Size: N/S". What surprises me, though, is that it was $189, but I guess that could have been any amount of time ago. The board didn't come with boots, and I don't know my boot size. Would you suggest getting new bindings and boots, or just boots? I weight 180-185lbs.
If it helps, I'm 6'2" and the board comes up to a little below my chin.
