Philadelphia, the three hour tour, the three hour tour

Part 1:
On our way to NJ, we decided we would stop off in Philadelphia for some sight-seeing and history lessons. We drove around downtown Philadelphia trying to find a place to park our van and camper. Many parts of that drive were scary and quite uncomfortable. We looked like the only crazy people driving around that area pulling something. Many of the streets were narrow and packed. We finally find a place where we can park our camper and van all at the same place, metered parking. The day happened to be a lovely slightly overcast day, with a small amount of precipitation falling from the sky. We were able to leave the dogs in the van with no worry of them overheating. Randy put enough money in the meter for three hours, so we have to make sure we can find our way back by then. We have no clue where we are needing to go, so we just start walking back towards the town. This is our first experience going to any sort of a National Park and we don't know what to expect. With a few directions from passersby, we make it to the main area for information and to get tickets to go on a tour of Liberty Hall. What an experience just being in the building. It was so nice and full of information. There were people dressed in period costumes, a first for us. I didn't know exactly what they were there for, I didn't know if we should ask them questions or stare at them or ??? So, we took a picture or two and walked by. We had a ticket for all of us to go on a guided tour. We wandered around looking at the area and in some of the historic buildings. We made it to the line for the tour and waited for a bit. Our guide was an expert in our country's history and was quite a character himself.
