Honey I have built in 'bun' warmers lol.. actually two years ago my daughter picked up a case of the hand warmers and a case of foot warmers for Steve. I think we used two, gifted a few out so lots left for those cold mornings. I checked on the weather year round, the average snow and rain and honestly the winters are a lot like up here in the Sierras it appears. will check back with you on that after my first winter. my luck it will the coldest winter in 150 yrs!
