"They go outside in white canvas space suits trimmed in duct tape. Their helmets are made from plastic light fixtures and white bullet-shaped trash-can lids.

Some people have nothing better to do with their time other than pretend they are on Mars. Have funn kiddies. Personally I like a good roller coaster.
