Hi Kandi, you are getting to Hucknall just in time, it shuts in March!
If I'm attending a fly in/air display or whatever I always try and be one of the first there for two reasons, you can make the most of the day and you avoid any clogging up of the circuit. Some fly ins have slot times, Old Warden and Duxford spring to mind but they are quite professionally done. Others it's just a case of turn up.
Do be careful, most pilots know how to do an overhead join (if that's what is required on the day) but there are a handful who will just barge in any old where because the sky belongs to them and you shouldn't have the audacity to get in their way.
