Have you looked into the costs associated with doing it very much yet?
Well, it becomes an even more expensive hobby if you aren't winning some money. $300 entry fees and $500+ in meat isn't something I plan to do 10 times a year if I'm not at least covering costs part of the time. I love to cook too, but I'm not going to drop $1000+ for the pleasure of doing it each time many times over through the year, I just personally can't justify it. More power to those that do, but you may have 60 teams in a comp and the majority didn't take home a dime. I too have no delusions of grandeur, and am just hoping I can cover costs once in a while and have fun doing it.
Also, as you mentioned the logistics, I found it to be a ton of work just in my driveway...that is definitely something to take into consideration as well. It's certainly a labor of love.
Edit - after reading my post, I wanted to make sure I wasn't coming across as negative. These are just some of the things I observed as I have been learning and preparing this year. If I would've known all this from day 1, I still would've done it. I'm just a pragmatic person.
