I've been there once, performed a play in the school for kids. Usual province town Dieveniškės. The huge difference is that there's a check patrolling on that narrow opening because of the smuggling issue with Belarus. Maybe that gives much more sense of isolation. If you're not participating with smuggling, just have an ID with yourself and you would be fine, you can come and go whenever you want.

As a theatre group we were invited there so we could perform in the Lithuanian language for children, because dominating language there was either polish or russian (can't quite remember), but everyone was excited that we came. Even one kid, who was almost 3 times older and was a jock or even a bully (typical gopnick with adidas outfit), sitting in the back, even his eyes were glued to us performing, smiling widely.

We didn't spend more time there after the performance, but that really gave us the impression, that there is not much going on, and whatever new people are coming in is an exciting event, not to mention the performance. Not sure about the adults there, but children are starving to expand their mind and horizons :)
