The comments about driving distance from LA crack me up. Last year, I didn't have much time off, so I flew down from Seattle on Saturday morning, my dad drove from Temecula and picked me up from Ontario airport, then we drove about an hour to Banning.
My dad and I had a great time and stayed at the Expo for about 10 hours. Then we drove almost 2 hours back to Temecula. A day later, I flew back home.
And it was totally worth it! Hoping my wife and I can make it this year.
