A bit off topic.
I have a little Minolta camera that I always carry on the bike.
The only problem is, the batteries freeze up. If I carry it inside my jacket, it' too much of a pain to take it out all the time.
So, I bought this little automotive baby bottle warmer, and plug it into one
of the SAE plugs in my tankbag.
Great minds think alike;small minds seldom differ...
