Yeah the ground was sturdy. It is a concrete floor in a heated shop, so I wasn't worried about the jack or stands sinking into the ground like it might on a hot asphalt driveway. I'm just glad I had the jack stand there. If for some reason I didn't, and the car would've come down on top of me, and somehow I survived that, I would've been screwed anyways, cuz nobody knew I was in the shop, and my phone was in the car.
