Why were hundreds of Italians driving from Szeged, Hungary into Romania at around 3pm on 30th July 2016? [closed]

This question may seem stupid or irrelevant but I'm very curious.

Last week I was traveling to Romania through Hungary, I was crossing border between Szeged (HU) and Arad (RO). Standing in the line to passports control, I was literally surrounded by Italian cars (license plates). After that, I travelled through Romania for next 8 days and I met almost no Italians neither in the mountains nor in Constanta area, so where they were all driving to? To Bulgaria? Some particular place in Romania that Italians visit?
