Jason *thinks* his dad is a good handy-man, but he once drilled a hole in a dishwasher's water line because he wanted to hang a towel rack so he wouldn't have to look at a tea towel on the stove handle any more. I figure anyone who makes an expensive mistake like that over something dumb that didn't need doing isn't allowed to touch a tool in my place. My father, while it *appears* he is doing the right thing also makes similar dumb mistakes. My mother is staring down a very expensive gutter replacement right now because he installed a bathroom fan incorrectly and the resulting ice-dams are destroying the gutters. I figure I'm smart enough to know when a task is within my reach and when I should call a professional. I think that is the key to successful home improvement :)
