Most likely scenario is that they drive around in their trucks waving both flags of the US and flags of traitors to the US, block traffic, and post to Facebook.
Worst case scenario, there is a wave a of hate crimes as these hyped up fascists try to "defend America" by picking fights with any random brown person they see.
Best case scenario, they try messing with federal agents, get arrested, and wont be voting in November.
I assume this is in reaponse to the weight of 90 kilograms? 90 kilograms is about 200lbs rounded up so probably more than just meth heads and Olympic gymnasts.
The first scenario is basically what happened with the convoys in DC a while back. Every day, they'd drive down, drive around a while, and then leave. I live in the DC area, but don't drive in DC often, but from what I heard, the impact was minimal.
I don't know how many trucks were involved, but I do know those trucks are expensive to buy and maintain, too expensive to keep running them in non-revenue service like that for long.
