boscomantico, that’s exactly what happened! I took off in EDSO without stickers and ended up in Portoroz WITH the stickers… otherwise they would have refused refueling my plane. I had to buy two of them for one Euro each…
Great report, thanks.
Did you have to get any permits for flying to Slovenia/Croatia in an UL?
Not at all, flying in most of the EU-countries is allowed as UL (except Romania I think).
