A week or so ago I asked where to stop in for some training in Arlington, VA. The greatest response was Ryan Hall's 50/50 gym. So, that's where I went this past Friday.
Turns out it was a good recommendation. I did an hour long basics class taught by Seph. Seph is a very clear and precise teacher. Everyone there was really nice and welcoming.
If anyone is going to Arlington, I highly recommend dropping in for a class or open mat.
Thanks to everyone at 50/50 for a great experience.
