Harry,
Yes, often moderate turbulence, occasionally severe. A tow pilot friend of mine, when talking about towing gliders to connect with wave, used to say: "The rotor's not rough unless you get rolled inverted!"
Besides spectacular flying in mountain scenery, we made another nice discovery, which you'll appreciate - the Three Ranges Brewing Co - "Putting the ALE in vALEmount"
