My dad raised cattle full size) few years back and his rule was 1 head for every acre. Kept 20 most of the time but now he is 85 years old and just has 3 miniature horses and donkey. I love going there.
Just a guess. Top row 4th Tyler, 5th Bill Cosby...jk.. Maybe Kravitz. Second row 1st J. Cougar, 2nd Petty, 4th looks like a Van Halen, 5th Schon, 6th Stanley. Third row 4th Otcasek? All this is a guess.
