I spend the day not too productive woke up very late around 11:00 was feeling very weak from the morning because of my duodenum pains. In second part of day me and wife decided to go and see the infamous National Museum Earth and Man (which is one of the most unique Very rare Earth Mineral Stones and Stalaktiti like stones museum in whole europe). Earth and Man museum is a must see for any scientist seriously involved into Geology. To reach the Earth and Man museum we catched Metro to European Union Station (from Mladost 3 to reach it we had to change train on Serdika station). To get a view on the museum there is a Virtual (Stones) Guide here
