Chris (aka Woody) Woodruff has organized a series of OData workshops to compliment the official OData Roadshow.
This is highly recommended. So if for whatever reason you can't make it to one of the OData Roadshow events, or you just can't get enough OData, see if you can get along to one of Chris' workshops.
The workshops start in Raleigh tomorrow and finish in NYC on June 28th.
