Thanks for the comments. I think "frugal fatigue" about sums it up. I decided to take a day off from being responsible, and we finally drove down to the shore--our only trip there this summer.

Gas about $15
Tolls $4.70
Air show at municipal airport, free
Lunch at airport $15
Beach, free
Pizza for dinner $10, at least it was bought with a coupon and we have leftovers for another dinner
Beer $5
Having our dinner in the back yard, free
Watching old movies after dinner, free
Not doing any laundry, cooking, cleaning, or shopping, free

For a total of $49.70. But like the ad says, feeling of complete relaxation, priceless.

Usually we go to a free beach, but this late in the season I could only track down 4 streets in Ocean City where there would still be lifeguards. I figured on biting the bullet and paying for their beach tags--but the Beach Tag Police were nowhere to be seen. The little building where you usually buy the tags was already boarded up for the season, and nobody walking up and down the beach checking for tags, either. A nice surprise.

I've got to start budgeting money for more outings like this...
