wow i'm glad when i was a kid noone cared what you did and no kid ever paid taxes and so forth.
here you don't even have to buy a license unless you cut inside city limits. you can cut outside city limits in the county legally without having a license. you also don't need insurance here to get a license. i dont' think the government is gonna come after you for what little amount of money you will be making. if you make 10k or less a year they don't really care if you pay taxes or not. it's when you go over that amount that they start to make a big deal about it all.
