Last time I went it was o'dark thirty, and the line to get in was down the street.
But, the line moves fast.
I've been going there for years, and they always have all the Vdub stuff close to the entrance. then it always has the next couple a rows of nothing but typical swap meet garbage, so I hot foot it down the main drag a few rows till I start seeing the regular type guys sellin their junk.
Some times I will even walk all the way to the back, then work my way back to the main gate. Since most people start at the first rows or so.
For you livin in Bako, I'd come down the day before and stay at one of the cheepo hotels near by (In San Dimas). That way you get there early and rested.
Also, look for this couple

They hooked me up big time last time I was there! Cool folks to, so maybe shoot them an email to see if they know yet what row they will be in.
