When I envisioned Larkspur, I saw a place new and fresh and clean, filled with hardworking, decent folk committed to making the town a success. So yeah, a perfect town. Milled lumber is a big deal for sure. One thin it would provide is straight roofing and flat even floors. I built the inside of my first barn out of small and medium-sized cedar logs... they worked good for the stall walls and fronts, and for the loft supports, but I needed good lumber for the doors and the loft floor. Lots of log cabins in those times had dirt floors and log and sod roofs, less than ideal for what Boone wants, so he'd be happy with Will Merrick's mill being so close and affordable. And yes, nails come by stage coach and supply wagons, something that became mass produced much earlier.
Boone and Coy are aware something is up with Phineas Lemon, so they won't be fooled. The bank is a big deal too. Banks by this time were insuring clients money, whereas before, if a bank got robbed you could lose all your money.
All in all, it's looking good so far. Thanks, Albert!
