Sunfish, you should give up aviation. Ramp checks are not confined to "events". They can be carried out anywhere. As noted above, if you have planned properly for your flight you will not have any issues unless you want to pick a fight. That said, in 47 years private flying and attending at events in several states I am yet to be "ramped" but have seen individuals who should be who have been woefully unprepared for flights completed or planned.
