class racing as a business?

Thanks guys for the advice. Of course we race for fun and will continue to do so. We were just making conversation on our way back from Dallas tonight after we went up to pick out our new motorhome. The thought was hey, we spend all this money to race (and enjoy it and will continue to) I wonder if we are missing out on a tax opportunity. If not, so be it. We look forward to meeting new people and making new friends.
