I found a map of DC.
Which side of the river do you mean by "this side"?
Why, the right side, of course!
On the upper right hand corner of the map, you will see New York Avenue. That is the route I usually use to enter DC.
It's an easy exit off I95, and also connects with MD Rte 50, which continues past Annapolis, and across the Chesapeake Bay.
I live North of Annapolis, and the BWI airport is about midway between Baltimore and Washington.
I know you went back for GWB's first Inauguration. Any chance you will be going back for this one?
