Yakima/Union Gap/Toppenish
At the end of last summer, my wife and I took a weekend trip over to Yakima/Union Gap. No problems while milling around those two towns, including the hotel, restaurants, and the old trolley (which we both got to drive).
After arriving, we decided to go to Toppenish (about 10 miles south of Yakima/Union Gap) for half a day, too. We ate at a Mexican restaurant, visited the train museum, and tooled around town looking for all the murals to photograph. I noticed a cop patrolling the streets a low speeds. Later, while I was standing out in the middle of a side street photographing a mural, he putted by and waved. I'll never forget his friendliness. While Tacoma cops respect my rights, they're not that friendly, in general.
By the way, if you're ever in Union Gap (Yakima), visit the Central Washington Agricultural Museum. It's a big outdoor "museum" full of old tractors and other machinery. Very cool!
