The service project was enlightening in two ways. One is that I learned Rock Creek is the third oldest park in the US. I did not know that. The other was how much trash was in the area that we cleaned. From distengrating plastic to a hub cap to bricks from a house, I wondered how long ago the items were discarded. It was sad to see how much trash was collected and how much more could have been collected if we had more time and trash bags.
