Louis, thank you for your information. I have searched the internet but couldn't find the historical reason. I have always thought that it was because of the weather. The end of July and the beginning of August is the warmest time of the year and therefore best suited for outdoor events with "lightly dressed" people. What I did find, however, is that there is also a leather pride in November. Never heard of that before.
PS Louis, what is going on with your address?
