18 teams participated at my state competition last year. The ribbons are for the 4th, 5th, and 6th place finishers at each event and first, second, and third place finishes for alternates. My state doesnt have invitationals either. Bryant what state are you from?
Here's an example of what the ribbons look like. This is my 4th place ribbon from Rocks and Minerals. Every place has a different color. First place is blue, second place is red, third is green and so on.
