Curt (son) had to work Saturday morning, but the plan was to drive here after work, arriving late evening. I was tempted to spill the beans to Mel a couple of times, but decided the surprise would outweigh any reason he might need to prepare for their visit. So, Saturday evening Mel fixed our dinner as usual, and after eating, Mel announced that he was going to check the water level. (rising/falling water affects the launching of the boat). I knew that they'd be pulling in at any moment, but said nothing as Mel walked out the door.
The timing could not have been more perfect if we'd had walkie-talkie communication. As Mel stepped out the front door, Curt was turning into our drive. Now, we live in an ultra remote area, and unannounced guests are very rare. Mel did not recognize the car, and when he saw who it was, was genuinely, and pleasantly shocked.
On Sunday Curt, Mel, and the two granddaughters went fishing. What a glorious Father's Day it was. There was the bonus of catching fish!
