I pretty much ride alone. My ex was 100% gung-ho about singletrack, etc... but my current has told me "I hate bikes! The mere mention of them annoys the h*ll out of me!" She likes *riding* but I end up going off on how excited I was about doing this-that-or the other thing, and she'll interrupt and say 'It's a money pit." blah...

So needless to say, if I get her to go out riding with me, even though I tuned her bike, she won't ride with a helmet (dunno if she has one, even) and won't borrow my gloves "I don't need those things! I won't crash!") ... so I singletrack alone.

I carry a cell phone on me "just in case" and leave a note @ home so at least within 8 hours, if something happens that I can't call, she'll know where I went...

On a related note- anyone know if there's a wrist-protector of sorts available? I'd hate to disconnect my wrists out there... I'm pretty young and limber etc, so I think I have my shins/ankles/knees covered... wear gloves... helmet (of course!) but... wrists are important, too.
