Unofficial, but very nice and huge greeting sign on A2 Riga-Vilnius road in Vilnius saying Laipni lūdzam Viļņā, which means Welcome to Vilnius in Latvian.
I should have been started this blog with this entry, when I arrived to Vilnius from Riga. :)
Russian language in Lithuania has its own features ;) E.g. interesting translation of Lithuanian word Skelbimai (ads) to Russian is Об'явления. Found in some apartment house of Naujamiestis.
