Be aware that the VFR charts for Latvia and Lithuanis (Not Estonia) are crap. They look all right, but many obstacles are missing.
When I was at Siauliai/EYSA with the Norwegian F-16 Det. in 2005 (ATCO) the pilots reported several massive radio masts with support cables >500ft that were not marked. Same deal, but to a lesser extent in Latvia. They stopped flying at 500ft after the first "woops" moment!
Our local parachute club had it's Skylane in Kaunas in 2002 for a re-spray, and the ferry pilot reported similar issues.
The Estonian charts are good.
