I've named my bikes, but nothing else inanimate.
I have:
Speedy (my triathlon bike)
The Tank (my touring bike- as in "heavy as a tank")
dirty (the mtn bike)

My grocery store mixte doesn't have a name. I don't know why- but it doesn't need one. I always say I feel like a granny when I ride it, so maybe it becomes "granny" one day.

I often get made fun of by DH, but he's started calling my bikes by their names lately. We went riding one day last week and he asked if I was taking Speedy or the Tank. hee hee
