After Jackson, we met up with a few other enthusiasts at this awesome Thunderbolt in Marshall. We've been wanting to check this thing out for a while since it does attack and people say it's super loud. This is only my 2nd time hearing attack on a Thunderbolt in person, and my first time since 2019, so this was awesome. I can also confirm that this thing is indeed loud as hell just as everyone says; it easily makes the top 10 loudest 'bolts I've been to. My meter topped at 118 dBA, and somehow Tommy's got up to 126.8 dBC, which can't be accurate but it is amusing to see how absurdly high his meter gets at some of these sirens. I would like to point out that this definitely doesn't top a certain 6M 1000 in another state in a town which also just so happens to be called Marshall. Nonetheless, this thing still managed to rattle the hell out of the ground and our chests, which is an insane experience. I really wish there were more 'bolts that did attack closer to me, because that growl on the wind-downs is hard to beat. Enjoy!
