'Tis better to fish alone...

...than wish you were. I have fished with no one but my dog for the past three weeks, and I can't complain.
You get first shot at the water, you choose where to go and when you want to leave, and your day won't be ruined by being out-fished (common occurrence around here).
Fishing buddies are good to have and important, but not just anyone with a fly rod will do. Most of us who fish hard are somewhat selective regarding with whom we will fish. I have an outstanding group of fishing buddies, but when they're busy - that's cool too.
One problem, however, is that you usually don't get the photos you'd like (see below). It's often the fish-on-the rocks-compared-to-the-net or -rod, or just the fish's head, or the fish in your hand as it droops away from the camera.

Incidentally, today I found a nice little spot where hoppers are working like gangbusters, far from the unending pelotons of the major rivers. I've never skittered so much - they would slash at it, then slash again. Then, they'd swipe at it, then slash at it another time or two. Eventually, you'd hook a fish. Makes me wonder if they were keyed on craneflies - I noticed a couple big ones.
