Yep, l've gotta buy some friends to keep me warm. And make sure you call him Mister!
I'm going to buy a Mr. Buddy heater to warm the van on cold nights. Others have recommended it on their blogs. The great thing about Mr. Buddy is he doesn't require battery power to heat. My furnace is a battery power hog (so l'm told), not that l have run my battery dry (yet), but l certainly don't want to do it when it's -20 out.
The candles are doing well for now, and l am using the furnace too. The other night it got down to below freezing.....burrrrr. When l'm sleeping all wrapped up, the cold doesn't bother me, l just can't be sleeping all day and night!
