Car Karma Question

So, a few weeks ago my sister came into town for a visit. We decided to make a day trip up to the Grand Canyon, which is about a four hour drive from here (here being Phoenix, AZ). On the way up, out in the middle of the desert, the tread on our front right tire exploded! The flying tire shreds ripped all this wiring out from under the hood, too. We figured out that the wires were connected to our front headlights, taped them to the hood of the car, changed the tire out for a donut, and cruised up to the next town. We found a very nice mechanic there who fixed the wiring problem for us right on the spot for pennies, and then sent us on up the road to the next town for new tires. The tire shop was closed, but there was a mechanic there working on his motorcycle on his day off, and he agreed without hesitation to sell us some new tires and change them for us. We ended up buying two new tires, since the other front tire looked like it was ready to blow as well. The two back tires were only a year old. Anyway, a few hours of inconvenience later, we headed back out onto the highway and made it to the Grand Canyon just in time for one of the most spectacular sunsets ever.

Here's the funny thing. Last week, my friends Russell and Sharon were in town, so I decided to take them on a day trip up to the Grand Canyon. We're driving up the highway as happy as can be, when my back left tire goes flat. Ran over a nail. So we (that is, Russ) changed it for a donut, cruised up the road to the next exit (on the advice of a friendly policeman who pulled over to help us out), found a tire shop, bought a new tire (the punctured one couldn't be saved), had them put it on, and then headed back out onto the road, making it to the Grand Canyon just in time for another spectacular sunset.

So the question is, do I have bad tire karma or bad Grand Canyon karma?

Either way, I appear to have good roadside assistance karma as well as some awfully good sunset karma, which easily makes up for either. I've got another trip to the Grand Canyon planned when my wife's family comes out for Thanksgiving-- I'll keep you posted.
