If you're planning on having happy hour at your usual watering hole you might want to consider joining us for a much happier happy hour, one where you'll spend less money on beer than you will for parking. The Observer is hosting a tweet up party at Anvil Pub (2638 Elm St.) to thank our loyal readers, Facebook fans and Twitter followers. We'll go ahead and include you witty commenters in that group as well. You're all welcomed to have a beer with us tonight from 6 p.m. to 8 p.m., and we promise the deals are worth the company of our motley crew. Fireman's #4 and Shiner are available for 5 cents (and that's not a typo), plus we'll have free appetizers and live entertainment. It's rare when social networking and actual human interaction intersect, but anything can happen when cheap beer and free food are involved. No RSVP is necessary, but you can let us know you're coming by sending a tweet to @ObserverDallas.
