Barb & Dave are our close neighbors at the Lake ……. spent many an evening getting together for dinner and games afterwards, especially her favorite ……. Rummikub! We always look forward to seeing their visiting families on the weekends. We’ve seen the grandkids grow up and become adults! We feel very thankful Barb invited us into their family 25 years ago! We’ll miss you, Barb.
