Should I make extra trip to winterize p-traps?

Shoot, it's only a 100 miles, on a weekend. Take a book & a beer. Treat the traps sit down and enjoy the solitude with the book & beer even if it's in a storage lot. Then drive home reflecting on the relaxation of your afternoon.....
or mumble and grumble all the way up and back about the waste of time and if only you'd rememebered to do it the first time and make a miserable day of the whole thing. Your choice, but I'd do it regardless.
