I guess it's a byproduct of my being an avid #artgeek and an early-riser.
Honestly, the summer season is so short (at least in Iowa), I refuse to let all these sunrises go to waste. I'm not only willing (and able) to sacrifice a little bit of sleep, but that's what my body seems to prefer. Heck, most mornings I'm awake before any alarms go off.
There are many benefits to getting outside early on a summer morning, though. Catching a beautiful sunrise is just a bonus.
