I have an idea, but implementing probably won't be easy.
I have 2 classic cars, that fight with Katie for my money. I use mine quite regularly, but there are people that keep them garaged and polished all year round. Therefore, the Federation of Historic Vehicles has introduced a Drive It day. The idea is that everyone who owns a classic car gets it out and drives it and uses it. It seems to work quite well and you see quite a lot of classic cars on the road for that day.
So, why couldn't we implement a crossdressing day, where anyone or everyone could dress up as the opposite sex for the day? It would be great publicity for us and may work towards a greater social acceptance of crossdressing as a whole!
I've no idea where to even begin with the idea of implementing it, especially without 'outing' myself in the process!
