Bryan,
I lived there for 23 years, both in Richland, West Richland, and Kennewick. The one thing that did bug me was the wind blowing the tumbleweeds and dirt around. You'll get that a lot in the spring especially. I grew up where it is green, mountainous, and mild in the summer, so when I moved over to the west side of the state and then on to Oregon I found I preferred it. Yes there are too many people on the west side, but I personally preferred it to the more conservative east side of the state.
I only went to the KH in Kennewick, though, so I don't have anything to tell you about KHs in Richland, I was trying to avoid them by that point.
Having said that, my best friend of about 40 years lives in Richland. If you guys decided to have an eastern WA get-together let me know, hell I might even drive over there for that.
Sherry
