I am moving and need some advice. I currently live in Pittsburgh and love having Frick park (a great park known for it's awesome mountain biking) inside te city limits and a short bike ride away. I am looking for a big city that is proferably in the east but an be in the middle of the USA. Also, it needs to have some mountains or giant hills cause biking on flat ground is damn boring. I also would like to have nice trails close or inside the city limits.
