Never went to it. When I lived in Applegate, we only attended the gun shows in either Nevada or Sac. Both of which had other antiques as well. I don't recall seeing bottles though. My guess, someone will have bottles as it looks like they have just about everything. I think its worth the trip (unless it costs you a tank of gas and a hotel). You never know what you might find.
We went to this in the early afternoon on Friday. Everything listed in the advertisement was there and as lpellegrini said, lots of interesting stuff to look at but very few bottles. Despite a small selection I was able to add a new California blob beer to the collection....plus get a good nap while my husband was driving!
