I go to a Tuesday line dancing absolute beginner class and practice by searching for the songs used in class on this site:
CopperKnob - Linedance Stepsheets
Included in the search results are the step names used in the dance, the step instructions (ie vine R = Step R to right, Step L behind R, Step R to right, Touch L beside R), and videos of the dance.
Also, you can find specific songs + info used in many of the classes at this site:
Villages Line Dance Community – Promoting Camaraderie and Friendship Throughout the Villages, FL Line Dance Community
I thought I knew how to line dance until I moved to TV last month. Showed up for a beginner class, and, after one song, a guy in the class, at least 10 years older than me, told me I should consider an absolute beginner class. I was a big fish in a small pond where I used to live; The Villages is chock-a-block full of really talented people, and I now know that if there's a class below beginner level...I sign up for it!
