Actually I knew a man who took care of my father in New Jersey for a year, and also a lady Jadvega who took care of dad before Ziggy did. Ziggy and his family actually planned the whole trip for me, and drove me around the country. I also met with Jadvega for a few hours at her grandson Evaldas' apartment in Kaunas. Ziggy's mom had a friend who was a tour guide and she took us around Vilnus and Trakai. It was so much easier for the first time to have a native person who spoke the language take me around, and probably next time I will do somewhat the same thing. However I have to say that navigating the country is not difficult as many people speak some english or other languages(russian,german, french etc) and possible you might know those languages also. If you know some lithuanian you will be fine. They have very good maps in the cities although you might get a little lost in remote places. After driving in New York City, traffic there is nothing. There is gridlock at some hours but main highways north south east and west are easy to get on. I would not recommend going alone but if you had a traveling companion who could read map while you were driving you'd be ok. In resturants menus are also in english and when in doubt just point to a dish or drink.
The money is easy...litas are about half us dollar, so it something is 20 litas its about $10 dollars. paula
