answer:The first and worst thing that would ruin your party would be if someone got hurt. So always, whatever else you do, consider safety of your home and your guests. That said, what do you know about bonfires? Have you participated in any before? The reason I ask is that “bonfire” is not “campfire”. You’re not likely to be toasting marshmallows on a bonfire! But if you’re going to have a fire in your yard at all you need to consider wind and weather conditions, relative drought and likelihood of fire spreading from sparks borne aloft and deposited far from the fire site (including neighbors’ houses, for example, or dry woods or fields), and you absolutely have to have water, sand, shovels and other firefighting equipment on hand, as well as first aid (and training) to handle the minor burns which may be inevitable. Spend 90% of your thought and concern for the safety of the event and all of the participants, and the fun will take care of itself, I think.
