Sprague Lake was surprisingly not busy, despite the fact that the lake is just right there next to the parking lot - accessible by a flat trail. Everyone should go on this hike, no matter how hike-phobic they may be.
When I was there, it rained a little bit, and I got to see my third rainbow of the day. I wasn't able to get any photographs I loved out of that, but I dig the lake anyhow.
