hmm its about mid october so i really dont know why anyone would go to Bulgaria just for frun at that time. too cold for the sea but still to early for sking in the montains.
but anyways. this summer i want to Borgas (sunny beach) and i realized that the BOJ runaway is about 500m away from the sunny beach Borgas road. there will be some land there but if u stop with a car no one should bother you.
people are not so obsessed with terrorism as in the US and i belive Israel. Basically if a cop stops you its beacuse u have done something stupid. if you can explain what you were doing maybe they will undersatnd you(use woulds like hobby and internet) but in the end u probablly have to pay a little "fine" because you are foreign. (sorry to tell you but thats how it works unless u drive a car above 50Gs)
I have gotten up cloase to 2 Tu-154 and Plovdiv but that probably requires you to have good Bulgarian and to know someone at the airport.
But anyways have fun in BG
. Try and go see the Sunny beach,nessebar and Sozopl. the drive from Varna to Borgas is about 1.5 hours.
hvae fun and contact me if u want for anything else
