Sorry, I haven't posted in a while. I just haven't been to very many tests that are worth posting.

This was such a nice siren to see; it had such a nice sound, and one I'll definitely be coming back to. Sorry about the camera shake; I was set up on a different tripod that doesn't have very good stabilization.
