When we started to build we started with how we were gonna start it. We tested out a bunch of things the could work and found the best one. Next we built how we were gonna finish it. Since we already knew how we were gonna finish it we got right to work. We wanted to build the start and end and fill in the middle. After we were done with the end we when back to the begin and added on. Then we added on to the end and found a way for each side to meet together. We built each part separately and tested them out. When we made sure that each part worked then added it all together.
