This is the first block I partially worked on in Las Vegas (not the one in New Mexico) during a Build the Earth event. I started building here on June 18th and worked on/off until the 24th. This block has 3 wedding chapels that I completed, Graceland, Mon Bel Ami, and Cappella Del Fiore.' I haven't worked with near-perfect 45° angles aside from a couple of standalone buildings, but I was satisfied by the outcomes.

There's also a town called Las Vegas in New Mexico, this one is in Nevada, although I put that disclaimer just in-case!
