My condolences for the loss of your Dad, I lost my best mate ,mentor and hero 10 years ago last January and still miss home ,I am lucky to have some old VHS videos of when we still had him,the thing I miss amongst others is when you are with your parents no matter how old you are you still feel young , I did anyway, I try every day to be as good father and grand pop to my family as Dad was, keep him alive in your memories and he will live forever
