Chaser's chagrin: picking a decent storm when a really good one forms near home

I watched on radar a northwest / southeast oriented line of storms marching toward our region this afternoon and noticed that the northern cells were maintaining the best organization as they propagated toward Culpeper.  Thus I chose that end of the line to investigate and plunged into the havoc of the Friday-of-Memorial-Day-weekend traffic to head first to Bealeton and then to just west of Remington.  The northern end was impressive enough as it approached a pastoral farm setting:

No lowerings appeared under the rain free base on the southern end of the cell, but a hail shaft was evident both on radar and visually:

Hail shaft to my west appears as the lighter area of precipitation slightly to the right of center.

My position is marked with the white "x"; hail marker is the green triangle.

Before the heavy rain arrived I motored leisurely through the town of Remington and stopped on a rural road outside of town to look back at the storm.  While I was doing so I noticed a very strong cell approaching the Fredericksburg area on the southeastern end of the line.  This cell, which eventually received a tornado warning, was THE storm of the day to chase and I was woefully out of position.  I tried to get back to the area in time but was unsuccessful...thus the chaser's chagrin.  But, I did chase today!!
