I don't know what the fuck it is, but somehow I almost always miss the Broadway exit off the I-10.
Now, I grew UP on that route. Coming from Mom's place in Prescott to Gran's in Tempe, I must have traveled that road over a hundred times. So there's no damn reason I shouldn't know it.
In college, this was a recurring problem -- I'd grab rides down to the valley with other people, and miss the exit and we'd be driving past the mall before I realized I'd fucked up and we needed to get off at the next exit and turn around.
Granted, all that was before I started driving on my own. And since I've been driving, I've favored other routes. But still and all, on the few occasions I HAVE taken the I-10 all the way, I've usually missed my exit. I got it right last night for a change, but then fucked it up tonight.
It's just weird, dammit.
