We were team 107 in 1997 (our rookie year). In 1998, we were renumbered as 93.
The reason there are 800 teams, and team numbers are up in the thousands, is because FIRST doesn't reuse numbers of teams not competing anymore. If they did, that would be a nightmare! He he - think about it: the announcer at a competition says, "And rookie team number 2 ... ..." Yikes. Not to mention the fact that it reissuing lower numbers to rookie teams would probably confuse a lot of people who have been around for a while!
