Today I re-aligned the rear triangle on my cross bike. I've been trying to figure out a weird tire clearance issue since I bought it, and finally some things clicked in my head after doing some measuring and I realized the whole triangle was shifted over to one side by quite a bit. It's much better now, but I've still got some tweaking to do.

My wife thought I was going to destroy my bike while I was pressing down against it with a 2x4. Steel is real though!
