I just spoke to a nice lady at the Antique Powerland. She said that the weekend of August 5th & 6th would be a perfect time for us to come since there's so much going on that weekend. See
http://www.antiquepowerland.com/html/steam-up.html. She also said that it would be best if we would all meet somewhere else offsite first, then drive to the Powerland together so that we could all park together in their parking lot. She said all the museums onsite would be open, including the truck museum. There will be lots of food vendors too, so no need to pack picnic lunches.
Here is what I'd like to propose for those driving far enough to need an overnight stay (like me):
Drive to Salem on Saturday and stay here overnight:

Drive up Hiway 99E to Brooks and over to the Antique Powerland on the other side of the freeway. Park together in the parking lot there. Have our "mini-meet" right there by the trucks, then enter the Powerland to enjoy the show. Note the $12 entry fee.
If anyone wants to suggest a different hotel, a different place to meet, or a different schedule, this is your opportunity! We should make reservations soon before all the hotels in the area book up.
