Opted out at CMH this morning. Post ID check they formed 2 lines, and alternated WTMD/backscatter as you came up. I was chosen for the nude-o-scope and declined. Agent had me stand next to the WTMD while he called for a male assist/opt out. I think I stood there for about 5-6 minutes until an agent let me through the wheelchair 'door'. No WTMD for me either i guess. I was told to identify my belongings on the belt, and was asked to wait while they collected them. Received pat-down, agent announced that he was going to use the back of his hand when he got to 'sensitive areas'. Free to go after that.
