Ok, I didn't read all of the above posts but I live and boat smack dab in the middle of virginia.....Smith Mountain Lake!
Our weekend place is actually within 300 yards of where many wardens put in/take out of....I've surfed many times in front of wardens there with a rope of course....until this year!
Wakesurfing is legal! It's under the "what's new" section here:

What's New
Type IV life jackets now only required on motorboats 16 feet or greater.
Recreational boats may carry visual distress signals in excess of requirement.
Wake surfing is allowable behind boats propelled by inboard motors.
