There are Black Freemason's lodges. Don't think that they are recognized by the main group, however.
My grandfather, a Mason, always rolled up his pants legs when camping or working in the garden, but I don't think it had anything to do with ritual.
I was once a DeMolay. It had its perks. When the Scottish Rite held their annual meetings, I would get out of school to assist in serving meals in the great hall. The temple had a great library. I especially remember a great illustrated set of the Thousand and One Nights.
