We are so sorry to hear about Jack.  For me personally some of his common sense advise was very helpful in my job a Mayor.   He was a good addition to Hillsboro.

The Lanahan family of Las Vegas will truly miss him. His smile , his love of life and  his written articles.  We wish we could be there to help in celebrating his life.  You are all loved and we are sending plenty of hugs.

We were so sad to hear about Jack. We will miss seeing him at the Wagon Wheel. He was so special. We loved his articles on sports. He sure cared about the kids.

I only met Jack several times, but I know his daughters very well, and they are all amazing testaments to Jack's (and Jane's) intelligence, kindness, and strength. I'm glad you got to spend so many happy, loving years with Jack, and thinking of you all during this very rough time.
