Excerpt:

As competition to host the new Lawrence Berkeley National Laboratory campus heats up, two of six cities still in the running are launching advertising campaigns to boost their bids.

Richmond rolled out its "Richmond (hearts) LBNL" campaign with buttons and a billboard off Interstate 80. Alameda is distributing lawn signs and hanging banners declaring, "Let's put the (Alameda) Point to work."

The two cities, which beat out more than a dozen other proposals to make it on the shortlist of six, are competing to host a sprawling second campus that will allow for future growth and accommodate 800 workers who have been pushed from the lab's cramped Berkeley hills facility and into off-site locations.
