Hello J., Well I dont know about any free places but ACS does a trick or treat town every year it is $4.00 or $5.00 per person and yes adults have to pay as well. But it is alot of fun and my kids have always had a great time. It is safe and warm. I know that this year it will be on Friday the 27 and Saturday the 28. I have always bought my tickets at the imaginariam (not sure on spelling) down town. Hope you all have a safe and happy Halooween. J.
