It's a good conference, put on by a national group called River Network.
Past River Rallies have been held in idyllic spots like the Columbia River and the base of Mt. Washington. But the Baltimore edition will be the first held in an urban setting, so I expect it will tread lots of new ground.
Should be interesting.
When: Friday May 29 - Monday June 1
Where: Baltimore Hyatt Regency (which is next to the Inner Harbor in downtown Baltimore)
