Tony - thanks this brings back memories and I will never forget that car. This video includes a clip of me falling in a puddle - some things don't change
There are several early films by my dad and also many other excellent videos on the MCRA caving film area of YouTube.

Aww! how cute....a little Ali... exploring and having adventures in caves...... even at such an early age!......

Tony, that is a real gem of an early caving movie, thank you for unloading this here.......

Brrrrr......my toes feel cold and my knees sore just watching this. Fab upload
