The Blaine Festival is a pretty standard city festival, but still a favorite of mine. They have special “shows” to watch – like a community dog show/contest, local dance groups, bands or pig races. There are several carnival rides and some food vendors (a somewhat small selection in my opinion). There are vendors, either for merchandise or information, some have the typical spin wheel games for candy. They also have a petting zoo with your standard animals like goats, sheet, lamas, cows; they had a fox to look at and bunnies to pet. This year kids could take a pony ride for $5. The weather was not great and crowds were light this year, I think that impacted the food. All the items we bought seemed to have been sitting under a heat lamp for a while. The park where the event is held has a nice playground for kids and many used it. The car show was moved this year to an off site location.
My favorite things to see/do have been the dog contest and the petting zoo, although I am sure people with older kids, or who like carnival rides themselves, would find that be an enjoyable aspect.
