Other notes: After Bismarck's 1003, we headed to Sheldon to catch their Fedelcode 5 for a noon blast. This one goes off for a generous 27 seconds which is nice. It was pretty punchy from directly underneath (117.8 dBA, 125.3 dBC) but definitely far from the loudest 5/7 we've heard. This one's mount reminds me a lot of the one in Centerburg, Ohio; and I'd say those two both felt pretty comparable from standing right underneath if my memory serves me right, which I guess makes sense, although Centerburg is higher pitched. It was quite windy here with some kind of strong wind gusts coming through at times, but thankfully, all my cameras' stabilizations seemed to have done a good job of reducing shakiness. Enjoy!
