Ready.....Set.....Paint

Well, it sounds good in theory.  I've signed up for classes at the local Community College, one in "nature drawing" and one in "painting from photographs".  I want to see if I can pick up where I left off 25 years ago which was the last time I seriously tried any artistic expression with paint/pencil etc.   I'm hoping it's like riding a bicycle -- you never really forget.  In any case, I think I'm prepared.
