No, you're not crazy. I drive 1.5 hours each way regularly to play pinball. Just 'par for the course' around here.
There is nothing wrong with having some time apart from the partner and the in-laws for some pinball. A bit of time away from time to time is essential, especially if they don't share an interest in the hobby.
In fact I thought about driving 10 hours to attend Pinfest Newcastle (Australia) in a fortnight, but was lazy and have decided to fly down for the weekend. It is going to be a solo trip and nothing but pinball for two days.
