Nothing (or very little) feels better in the morning than beating the UMF. I felt this morning that it was going a little too well, so I peeked out and glimpsed the enemy of my winter mornings. Quickly I ran out and started the car, just in time to make it worthwhile once the kids and I finally got out there to leave. So the UMF to DMF (discovered morning frost) conversion energized the morning and it's gone not so bad since, contrary to the norm.
