I have noticed that there's quite a few providers, both ind & agency, have left town for vacation. There's also more promo on the LA Ad Board. I am wondering if it's the normal summer slow down or it's a sign of economy slowing.

I think it is a normal slow down and many providers know in the summer it slows down in many cities.
Maybe they decided to take this time to have a vacation,take a break,etc.

That's good to know. Note to self: save more year end bonus for next summer.

I see no difference between winter, spring, summer or fall. Go figure!

am in town i maintain the same pattern as often and whenever I can, rain or shine irrespective of how busy the 405 S or 10W are.
