I never had the opportunity to meet Roy L. Johnson in person. I did have the honor and enjoyment of visiting with him regularly on the phone when he called to make reservations for his daughters to come to Kerrville to visit. On behalf of myself, my family and our drivers at Hill Country Limousine Service, Inc. we extend our sincerest and heartfelt condolences to Mrs. Johnson, her daughters and family - God Bless you all.
