Out of Croatia into Slovenia again

A long queue at the border control and "big brother" cameras checking that the vignette is valid for motorway travel. The second one being a possibility for the Irish border after Brexit?
A nasty accident on the opposite carriageway caused miles of tailback traffic and looked as if it had ruined a young family's holiday. poor things!
At Ljubljana again tonight. No idea where we might be tomorrow as we eventually head west!
