Five hundred miles isn't that far to drive.
Yes, it's not hard for a person to drive 500 miles. It is difficult for more than a dozen people, along with gear and equipment, to travel 500 miles. And they had to seriously hustle to get there, find the place, load in, soundcheck, etc etc etc before they're set to go on stage, with no margin for error or the show is cancelled. And then they had to immediately get back on the road and drive 1,100 miles.
In fact, they're probably racing down the road right now because that show that's 1,100 miles away is in just a few hours. In less than 96 hours, this entire group has driven at least 1,600 miles and played two shows. Maybe that's not impressive to you and maybe you've never done anything remotely like that.
