Yes, we did go and investigate the hole after a short while. We walked around the tree and looked up into the branches etc but there was nothing there. I don't think we looked for footprints but it was the middle of a field during a hot summer so I doubt there were any. This was 1970 and I was 13, so I didn't own a camera. Very few children would've back then. My mother didn't own one either. Liz's Dad had one but I'm pretty sure he wouldn't have let her borrow it to go on some "wild goosechase". We told a couple of other friends at school but were laughed at so we decided to never mention it again.
