I like snowboarding but it has been a long time since I have gone.  I do live in a place where it snows so I should go more often.
I have never been snowboarding.  Is it similar to snow skiing?
It is similar to skiing.  You have the board attached to your feet but there is only one board for both feet instead of one long board for each foot.
So do you snap boots in?  I pictured it more like surfing, with feet freely on the board.
Snowboarding actually came from surfing but yes, you do snap your boots into the board.  My guess is it is harder to keep control with all the gear on compared to surfing.
Which gives you the best speed?  Skiing or snowboarding?

I feel attached to that country because it is where I learned all my skills."
