Around the turn of the 19th century, Sonoma Valley and Springs area were popular tourist destinations attracting weary city dwellers eager to illicit the benefits of hot mineral baths easily accessible by train.

Visitors would write home to their families on postcards that featured the resorts and sights to see in the region - destinations like Agua Caliente, the family resort; Fetters for a more party-centric crowd and Boyes the upscale resort with fine dining and golf.

These postcards give us glimpses into what the area looked like before vineyards dominated the landscape.
