Welcome to both of you. As far as being nuts,.....I could say the same thing about photography and golfing....
Oh...that is ME that I am talking about, too!!
All hobbies create an aura of "insanity" when fully pursued. Here, we think it is normal. You are in good surroundings. My wife, of many years, has learned to just let me enjoy whatever my hobby of the month is.......it is better than booze or blondes..I think.
