Is it a good idea to visit a company before contacting them?

<p>I'm having trouble finding contact information about a company I would like to work at. It's just down the street. Is it a good idea to just pop in and ask for information?</p>

<p>Why don’t you pick up the phone and give 'em a call?</p>

<p>Read my post, not just the question.</p>

<p>What, you can’t even find a phone number?</p>
