My earliet memory of being fully dressed up was at he age of 11 and in my 15 year old sisters clothes and wig. Let's see that would have mede 1964 or 65. I remember at about the age of 14 going out in the backyard drerssed late at night, probably 11PM or so, not really daring but our side yard was on a main street so I am sure I was seen. A few late night drives at 17 were the next step but the first time I "really" went out was at the age of 23 to a drag show.
