and did psychologist solve my problem 100%?????????????????
Contact your local fire service (not by using the emergency numbers) In some countries there is a small fee. In other countries (the UK too I think) it's free.
I agree with most of the answers, great ideas! Just make sure that if they arent your kids and there are horses involved, get everyone to sign a waiver. :) Hate to be a downer but, to go through all that work to have someone fall off and get hurt and try to sue you Cover your bases and enjoy the party!
