This Sunday, I am leaving for Sofia, Bulgaria. I work for a bank as a software developer working in Microsoft .NET technologies. About 1-1.5 years ago, my bank purchased a European prepaid card company whose IT department is located there. Their developers work primarily in PHP and I'm heading overseas to help cross-train their team to work in .NET so that they can share some of our project workload. I'll be there for two weeks and obviously won't be working 24/7. I'm looking for suggestions of things I can do and sights I can see if my off time. I'm hoping some of my fellow forumites can help me out, particularly some of my European Spydie-brothers.
