Two weekends ago I attended and gave a talk at PyOhio 2014.

I'm really quite impressed with the how well organized this free conference was. The talks were high caliber. The conference drew attendees from a pretty wide area. Most folks I ran into were from outside of Ohio [1]. There were several rooms for simultaneous talks, one of which was set up for hands-on tutorials, which took place throughout the 2-day conference. Video recordings were made of the talks. There were lots of interesting talks.

I really like the balance they achieved between accessibility (low cost, weekend schedule) and professionalism. This reminds me of the early days of Python conferences but with more polish. [2]

[1]I was bummed that I didn't run into anyone from my home town of Cleveland.
[2]This isn't meant as a slight of PyCon, which also does a great job.
