Most of the time. Did forget now and then, but like you, we'd arrive when there were little or no cars and it wasn't a problem. Don't know what it's like now since we haven't been clipping the passes to our packs.
Just seems silly to clip the passes to the pack when most of the day you're not with your pack. Not that I expect to meet up with a ranger when I'm walking off, but at least now I have my pass with me all the time.
