Turning Tricks for the Ol' Folks

Hey, today I made some quick and easy money, which made me rethink my career choice... I got $40 for snowblowing 2 driveways, about 1 hours work. Now, all I need to do is scope out some neighborhoods where a lot of older people reside. Then I buy a house, and a snowblower. Then, when storms hit, I go blow out my driveway when lots of old people are out shovelling, prompting them to offer cash for my snow clearing service. The Snowbloer would pay for itself, and I'd be filthy rich! All in theory of course...
