Obamajam was definitely worse than usual on this last visit. Thursdays are already the worst traffic days of the week and his visit to Burbank prior to driving to Hollywood for his Jimmy Kimmel appearance (hilarious by the way) and then heading over to Santa Monica made driving anywhere in LA a true nightmare.
There has got to be a way to only allow presidential visits on light traffic days. Weekends are ideal, and Thursday and Fridays would then be off limits to visits. :)
