It can get very hot and easily have 30°C - 38°C for a long period of time. Those temperatures are also what the forecast for August says. So pack lots of light fabrics, tops, t-shirts etc and if your skin is sensitive, don't forget the sun block if you plan to do lots of outdoor activities. You don't have to carry lots of film rolls, you can buy them in most stores.
If you use a digital camera, you can go for example to 'Walgreens' with your card and get there within ca. 1 hour prints of your photos or a photo CD. Walgreens is just an example. There are other stores in Rancho C. that offer the same service.
The food was alright but the location seemed a little smelly and the service wasn't too good. Sirloin steak with fries. Don't ask for it "well done" or you'll get it almost burned. If you wanna try their mudpie, just ask for one and share because they are huge ;-)
Once home to the Kucamongan people that were family of Gabrielino that were one of the largest tribes in North America. When the missionaries ventured in bring in prosperity and place where settlers could find supplies and rest. It wasn't till in 1839 when Don Tiburcio Tapia, a successful businessman/judge from Los Angeles, filed an application with Mexico’s Governor of California, for a plot of land called Cucamonga. Tapia was granted 13,000 uninhabited acres between Pomona and San Bernardino. He started a successful cattle ranch and building a large adobe home at Red Hill. Tapia also started the Cucamonga Rancho Winery, California’s oldest winery.Then in 1850's when California found statehood, the old Spanish Ranchers found themselves having financial difficulty. The Tapia's sold the ranch to Alabama-born John Rains and his wife Maria Merced Williams de Rains who both bought the remaining lands and winery. They expanded the winery lands, until sadly Mr. Rains was murdered and Maria left the ranch and it went into foreclosure in 1870, but then sold to Isaias Hellman and other San Francisco businessmen who later formed the Cucamonga Company.
Not soon after that brought in wagon trail over Cajon Pass to the Mission San Gabriel in 1826, the Butterfield Stagecoach line in 1858, the Union Pacific Railroad in 1887, and the Pacific Electric Railway Line in 1913. Yet it during the 1920-30's brought in paved roads and Route 66. Rancho Cucamonga is considered on the Inland Empire's premier City that sprawls out near the foot of the San Gabriel Mountains. In 1977, three communities Alta Loma, Cucamonga and Etiwanda combined creating the City of Rancho Cucamonga.
