My daughter-in-law is the assistant archaeologist for the city of St. Augustine, FL. They're digging on Aviles Street, trying to prove it's the oldest street in the continental US. They're finding ammo. Old ammo.
I told her that I don't think that it's the oldest street in the US, because depending on how you define the term, Junior has an ancient buffalo road running through his property. It's been used by buffalo, Native Americans, settlers, wagons, stagecoaches, you name it. It's certainly older than Aviles street in St. Augustine. However, Aviles street may be the oldest planned street in the US.
At any rate, my daughter-in-law has a really cool job.
