I sadly missed out on one which was absolutely perfect for me in terms of making money and learning at the same time. Namely fibre glass moulder (layer, whatever you want to call it) for boats. I could even have asked my grandfather for some advice as he built his own boat from fibre glass years ago.
Damn, I wished I got that job as most of you know of my glass/carbon fibre antics and it would be a very valuable learning time and best of all get paid for it instead of only spending it.
Anyone of you have fond (bad ) memories of summer jobs?
