My wife is very attractive and we're very accommodating, I can't imagine it being any better.
When it comes to swinging meetups, distance matters. Four hours each way is a heck of a long drive. It might work for one or two meetings but that's about it, no matter how hot the wife is.
It's funny that people say it's not a long drive and that it's doable but when it comes to actual reality, sitting in your car four hours each way is just too much. Better to find someone closer.
