It's that time of year again! Comic-Con 2012 launched today in San Diego, California, and will run through Sunday, July 15, 2012. As the world's most popular comic book trade show, it's sure to be an epic event.

And what's the most important item at a convention of this size? Promotional bags, of course!

This year, Warner Bros. Entertainment supplied official bags that attendees can use to carry the freebies they pick up during the show.  According to CBS News, "The totes will have the Comic-Con official design on one side, and the other will spotlight different TV shows and movies."

"The bags are just so important for getting through Comic-Con," convention attendee Sony Chabolla told the San Diego Union-Tribute. "I use it to put free stuff in, but I also buy comics and figurines and I put them in there."

Chabolla may not realize it, but she explained why trade show giveaways are so important -- not only are they used at the event itself, but they live well beyond it. Did you snag one of these highly sought after Comic-Con 2012 bags?

What happens to functioning car parts after someone's decided to trash their vehicle and buy or lease a new one?  Unfortunately, many reusable pieces become mountains of waste in landfills if they're not recycled properly.  But one organization aims to bring together auto recyclers across Ontario to limit waste and promote the use of quality recycled green parts.

The Ontario Automotive Recyclers Association (OARA), which was founded in 1992, keeps auto recyclers "informed and involved with input and information into current industry trends and government legislative initiatives that affect auto recyclers."  If you're interested in learning more about the OARA, you're in luck -- the organization's annual trade show and convention will take place March 29 - 31 in Toronto, Ontario.

Unfortunately, if you're an auto recycler looking to exhibit at the show, it's too late.  According to Collision Repair magazine, all spots have already been filled.  Steve Fletcher, OARA's Executive Director, told Collision Repair that this year, exhibit spots filled up quicker than ever.  "We always sell out every year but never this soon," Fletcher said.

For those looking to attend, there's still time to register.  Attendees can look forward to "constructive knowledge sharing and features educational seminars, presentations and industry round tables combined with interactive social events and a busy tradeshow floor."  Plus, promotional bags and other giveaways will be provided!
