Lost opportunity

I forgot the e-collar on our Saturday hike at Lake Allatoona.  Larsen's "sits" are getting better, but are still slow and begin first with a tentative crouch and not with a committed sit.  The e-collar makes an instant correction from afar, no different than the pop on the 6-foot lead when doing heeling work.  As with the 6-foot lead, the trick is in timing and being fair.
