TL;DR
A trip across a big campus can be the hardest part of the day for people who use wheelchairs, tire easily or struggle in heat, cold and rain. In San Antonio, a tunneling machine started digging on Nov. 10 on a nearly mile-long tunnel meant to carry visitors underground between a hotel, the Morgan's Wonderland campus and two care sites, out of the weather. The Boring Company, Elon Musk's tunneling firm, is doing the work, and an anonymous donor is paying for it. It started this dig 29 days after finishing a test tunnel in Bastrop, Texas, a rough measure of how fast its machines can move from one job to the next. Small, privately paid tunnels like this one could become one of the first everyday places people meet the company's machines. Our odds that the tunnel opens to visitors by 2028 are 50%.
