I cant recommend highly enough taking a lesson right off the bat. That way you dont have to unlearn bad habits you are almost guaranteed to get on your own. If you can afford it spring for a private lesson. Check out your local resort because some of them offer deals on private lessons at certain times. The other option is to book a group lesson mid day mid week and be one of if not the only one in the class.
Take a lesson. You will never look back and wish you didnt.
Agree, with one caveat: As long as you get a decent instructor.
Above statement is certainly true if you get wolfie, etc. Not so much if you have some of the instructors I had early in my riding career - and I still see plenty of similar types around the mountains these days (well, not in the areas that I ride, but you get the drift).
