Info for Moldavia and Rumania

Who could give me info about these two countries? Where and how did you manage to camp?? Special difficulties? Unsafe places? Can we get the visa for moldavia on the border? Is it a country you would recommend in term of landscapes, nice contact with locals, security on the road and possibility to camp (or find cheap accomodations)? Is there anybody who crossed it during wînter time and could give me his feeling?
