i worked in the forestry for years as a tree feller in the 1980s hard work and not lot of money but really enjoyed it ,like you say no paper work just grabbed a saw and tuned up,.worked with one lad who really worked fast but looked like a patch work quilt he was covered in that many scars ,its a dangerous job especially if you were felling on a slope , used to do a lot of work doing fire breaks ,I used to work for a sub contractor for the forestry commission basically all the out of the way places that were dangerous that that they didn't want to do themselves ,used to get bit to death i
