+1 on Sleeping bag.

My timing belt broke last week. Spent 2 hours waiting AAA.
wrapped spare coat around legs, lit candle on dashboard, popped handwarmer.

Was about to break out sleeping bag at 2 hours, when Tow Truck arrived.

Found one odd gap-- my book read had plenty of power, but conflict between turning pages and keeping on gloves-
gloves were
A) too big
B) not conductive

think I might need to starting carrying a stylus for when I need to wear gloves..
