I love how that happens, and it often seems to be the same faction of people that say "I'll believe it when I see it." We had one guy in our office who kept telling a Canadian friend how Canada's system didn't work, yet she had life-saving surgery because of it. He'd tellme how solar power is ineffective. I'd tell him I've built houses through Habitat that have solar power, yet I've visited those houses since the families have moved in, and the solar is a great advantage to them all. He said he needed proof. I told him where he could visit, and he didn't think visiting those houses counted as proof.
