Youngest and I went on a short hike at Arcadia Mills Archaeological Site. It is open sunup to sunset and is free to the public. (except for guided tours).
A lot has changed since we were last here. There used to be one boardwalk area, then a footpath on somewhat rough terrain and a scare the hell out of you suspension bridge over the creek. That has all been replaced with a boardwalk and steel and wood bridge over the creek. There is still a short footpath of about 1/2 mile. We trekked it all today.
