Word-of-mouth leads in Cleveland (update)

A friend who works at a local manufacturer says there are openings not advertised online. It has been weighing on me all week. They like a brief email with a résumé. Should I visit in person?

Thanks for writing this out. I went through something close to it 5 months ago, and it settled down once I kept a simple log of every call and form.

Keep a list of who you contacted and when. It makes follow-ups easy.
