Although it is uncommon for a child of the age of 13 to be involved in things such as horse racing, there are certainly a few who are. For these few kids, it might be very fun to have a Kentucky Derby themed bar mitzvah party. In this type of bar mitzvah party, you might want to hire a few horses for the kids to ride around on. You could set up booths, where the kids could line up and take the horses around the block or something with a trainer, just to see how it feels and if they like it. After this event, you could all the kids go inside for a bit of food. You could make horse shaped cookies for the kids to snack on and you could have pasta that looks like hay and other things that resemble things that horses eat. All of the plates and silverware could be horse themed and the walls of the place where the kids eat could be plastered with different famous horses and pictures of different famous races. Party invites for a Kentucky Derby themed bar mitzvah could be very interesting. You could hire professional card makers and have them create a bar mitzvah invitations just for this special occasion. You could ask them to create cards in the shapes of a famous horse, or in a specific shape so that the card itself literally spelled out Kentucky Derby. So get out those bar mitzvah invitations and get ready to saddle up for a great time.
