I do realize that those living in Seattle, Stirling or Stavanger will find this most amusing, but here in San Francisco, "long" summer days are rationed. Sure, we enjoy mild, friendly weather for much of the year, but you guys have the last laugh with your extended summer mornings and evenings.
My pathetic sluggishness of the past few weeks means many light mornings have already slipped by me, so I am determined to make the most of what's remaining. Somewhat to my dismay, we are already past the summer solstice, the longest day of the year in the northern hemisphere.

If these sun-lovers could achieve something of this scale and accuracy with the resources available to them around 4000 years ago, then the least I can do is hop willingly out of bed for a gentle dawn run.
