Birthday boy

Celebrating my dad's 75th birthday today! Just with the closest family, and a lot of good food :)
My dad's special way to party was to take a day off from work... You know, the official age to retire passed already a while ago...but as self-employed, one can work as long as one likes. Tomorrow he is hitting the road again. At 4 am...
I guess one can say that he is young to his age ;)
