California Living Museum (CALM) is having their annual Trick or Treat event on October 28th starting at 10 am until 4 pm. Not only can your kids enjoy looking at the animals and playing on the small playground, but CALM will be having games, crafts and treats. Kids under 3 are FREE and kids 3-17 can get $1.00 off admission if they are in a costume.
I have to be honest, If you've already been to CALM, it's more fun to go during these kinds of events because CALM is usually always the same, which is fine but it's a small place and even when years have passed, I still feel like I had been there yesterday because it hasn't changed much.
Prices for adults are $6.50 and kids 3-17 are $2.50 IF they are in costume.
