North on Interstate 5 to exit 306B. (bout 3 miles from downtown as the crow flies) At the light turn left. Bear right at the stop / yield sign. Turn left at first available. Turn left almost immediately and you are on the entrance road. (I-5 to entrance road < 1 min)
Entrance fee is $8.00 to watch, $20.00 to drive (you have to pay a one time fee $10.00 for a drivers card and number unless you already have one.) They check your vehicle for alcohol before the pay booth. (Pop trunk etc.) They don't give me much of a hard time. Only alcohol I bring is for the car ne hows.
Hope to see ya there .. but if not have a good time in PDX ne hows.
Wish I had more suggestions for ya on places to go but I don't get out much.
