I just received an email about this too!!! I am going to attatch a copy of the program to this event so that you can find a meeting place easier. It also lists all of the free classes that are going to be available each day.
This is being held in the area where I grew up 8)
The fairgrounds are just North of Vancouver/Portland on Interstate 5
The exit is clearly marked and is very easy to find, you can see it as it sits right next to the freeway.
I am hoping to get down there to it, but won't know for sure until Tues or Wed.... I would love to meet up with all who are going though!!! :D :D :D
