Oh boy @Oblio
! You and I could talk ! I too pored over the Innes book when I was in grade school. My Dad got me the book in the 60's shortly after I got guppies and my first aquarium. Dad grew up in Philadelphia so was probably aware of Dr. Innes because he was always telling me about the aquarium he had back in the 30's. Model Rocketry ? Never read any books about them but I sure burned up a lot of Estes engines and crashed a lot of their rockets. Now let's talk about Colin Fletcher. I did a lot of backpacking in my younger days and The Complete Walker was my bible. I've read The Man Who Walked Through Time and The Thousand Mile Summer is still on my reading list. Looking forward to that. Terrible the end that Mr. Fletcher came to . Great reading and great books from great authors .
