I'd also like folks to keep in mind that memories of a small child are exactly that-- a small child...perspectives & proportions are seen differently thru the eyes of a little one.
For example, I have memories of a huge, cavernous-sized bedroom with a ginormous bed -- however, seeing that same bedroom as an adult, the room is actually small -- smaller than any bedrooms in my own home...and the bed was standard size -- not queen or king.
It may be hard to figure out distances because 100 yards could seem like a quarter mile to a little kid.
Just my $0.02.
Yes, and that could be the explanation for the giant "300 pound man" as well. He could have been 5'5" and weighed 150 and he would have seemed huge to little girls.
