In all of our (five) years living near the BNSF railroad, we've never had the opportunity to see track maintenance up close. Until today! If that doesn't sound like a treat, you're obviously not Will.
He watched, enthralled, as machines replaced old ties and smoothed ballast around the tracks. Aside from that, I have no idea what was going on.
You'd think our boy was in charge. Get back to work!
