Oh my, the time of my life and the funds available did have some impact on what I was "in to" at the time. To list a few,
Luthier made Archtop guitars.
Good wines from CA. and Bordeaux.
Biking. I have done all of the old former railroad track trails in Wi. and biked the majority of Door Co. Wi.
Most things Chicago, esp. Jazz bars.
Modern Architecture
Modern era furniture from Hans Wegner, Charles Eames and more.
Computers, to an extent.
When I owned my business I was very into giving back to the community and enjoyed helping many that needed help, not a hobby but a major interest.
When I was more into traveling, I enjoyed art museums, mostly those with modern art, like MOMA, Lousiana north of Copenhagen and others.
Photography, from the old Nikons to more modern digital.
I did have a few nice cars, Porsche, Lotus and others, but the Formula Fords at Road America were the fastest...and cornered the best.
But in my adult life my children and other family and friends have been my greatest interest.
Good thread, and enjoy the responses. And I did spoil myself with a few nice watches...which my sons now have.
