Sounds like you had a good time. Thank you for sharing.
It's always interesting how fatigued one gets in a class type environment. The combination of environment, weather, mental pressure, and physicality definitely can wear on a person. At the end of the day, the classes I have been in, you can tell our brains were soaked up with knowledge and body language just showed how exhausted we all were. The ironic thing is that is when accidents happen and we had to stay as sharp as possible.
