When I got called into Boeing for a job, while I was interviewing for the first job another offering came in at the same time. It was to crawl inside the fuel bladders and inspect. Just one prob with that job. I couldn't fit through the access hole. They had one laying on the table I said let me guess this job is crawling inside the fuel tanks LOL they said yup. I didn't get that job...........

Realist - Everybody in America is soft, and hates conflict. The cure for this, both in politics and social life, is the same -- hardihood. Give them raw truth.
