Alice, In this day and age, hats and tee shirts are the billboards of youth. I think what you are planning is the first real positive workable aproach I have heard yet. Way to go. I heard this tonight " if you ignore your they will go away." It pictured a young man sitting in a chair with cuffs on his wrists. I have been taking my kids with me camping since they could breath. We have a good relationship and they have learned to respect other people and property. My son lives to work on cars and his tee shirts and mine refleck our views toward what we like. I think you are on the right track.
