Yep. I can handle the 20-30 minute walk, especially if it means my chance to exit the parking lot doesn't depend upon my ability to cut people off... I mean merge. I'm of the opinion "anywhere but Irvine" if a group is playing more than one show in the LA area, but I came to Irvine because I first saw NIN here, so I have some nostalgia.
I just turn right onto Irvine Spectrum, right again on Bake Parkway, then right on Lake Forest, and onto the 133 North to either the 405 or 5. Never had issues with traffic getting onto the freeway.
