There's is some interesting history in my home town of Elk Grove. This sign highlights some of the key historical places of Old Town. I've lived here my entire life (since 1979) and I've seen so much of this town change. The final cache is not at the given coordinates. Everything you need to solve for the final cache location is in the sign at stage 1 and in this cache page. This is a field puzzle so you must be on site to solve. Or I suppose you could visit the location, take a photo of the sign, solve it at home and come back. Enjoy!
