Real MILFs - The strangest place I had sex has to be in a park at night on a jungle gym seems a little weird. Less weird but more public, in our car in the side parking lot of a local food market, ending up outside the car with me bent over the hood as he finished. Does a not-in-use private dining room at an otherwise very full upscale local restaurant counts as weird? The manager who suprised us, suddenly appearing with another couple to show them the facility, didn't exactly use "weird" as he disapproved of the goings on!
More public and semi-public places than weird, I'd have to say, but then I'm sure what anyone means by weird!
