A special celebration...
While enjoying an early morning breakfast in a northern Arizona cafe, four elderly ranchers were discussing everything from cattle, horses, and weather to how things used to be in the "good old days."
Eventually the conversation moved on to their spouses. One gentleman turned to the fellow on his right and asked, "Roy, aren't you and your bride celebrating your 50th wedding anniversary soon?"
"Yup, we sure are," Roy replied.
"Well, are you gonna do anything special to celebrate?" another man asked.
The old gentleman pondered this for a moment, then replied, "For our 25th anniversary, I took the misses to Tucson. For our 50th, I'm thinking about going down there again to pick her up."
