One improvement I noticed when I arrived at MSP late last night (after 4 hours on a snowy runway at DTW) is that the lighted signs were operating appropriately, with the North CP sign displaying NORTH CHECKPOINT CLOSED and the South showing as open.
Thanks. I don't opt out but I nevertheless like to avoid the nude-o-scopes as much as possible on the grounds that, given how often I travel, I'd rather not expose myself unnecessarily to whatever health risks are involved. This means I'll walk to another checkpoint but I don't subject myself to a grope, er I mean patdown voluntarily.
