Everybody knows about the Indian summer which is famous for it strong and shiny atmosphere in the woods. That is why i wanted to see it too. So, last Saturday morning we left Boston and drove North-West.
Mine too... I will be there next week, got tickets for 1/4 and 1/2 finals... Hopp Schwitz!!! Let's go for a drink soon. I want to meet your girlfriend too! I heard that she is wonderful and pretty.
We went to eat dinner at an Indian restaurant an my wife and I were afraid that it would turn our stomace upside down, just a day before we had to take the long train journey back to the capital.
