I was once a student at a community college taking an astronomy course and was required to visit an observatory to write a reflection piece. I ended up visiting Mt. Wilson Observatory. Boy, did I think my beat-up, 2002 Honda Civic coupe would not make it up there due to the incline - my friends and I were in awe of how we were driving "in the clouds" (or maybe it was just fog?). I loved it up there! If I recall correctly, they had this shack where you could buy your tour pass and food.
