Was It the Ghost of a Miner?

At the end of this past March, my sister, her boyfriend, my husband and I took a trip to Bisbee, Arizona for a weekend of camping. Bisbee was known as a mining town throughout the Southwest in the late 1800s. The Copper Queen mine opened up in the 1880s and the town became populated almost overnight with miners, saloon owners, and ladies of the evening. A lot of the original miner's cabins are still standing and there are quite a few stone foundations left from the ones that have crumbled. These foundations dot the hillside like a rugged constellation.

In 1975 this mine closed for good ending an era that more often than not, contained three or more generations of people that had worked there. When the miners moved out, the artists and hippies moved in creating a laid-back, fun and historical place to visit and shop.

After an afternoon of sightseeing, the four of us returned to our campsite that was stationed directly to the left of the Copper Queen Mine. There are tours that still take place in this now defunct mine and to give you an idea of how close we were to the mine, we had to cut through the mine's parking lot to get to our campsite. After enjoying s'mores and some music, we decided to all turn in for the night. My sister and her boyfriend slept in a tent, and my husband and I turned in to our camper. I had left the door unlocked just incase my sister and her boyfriend might need anything during the night. I often read before going to bed and did so this night before I started to get tired and decided to turn off the lights.

While waiting for sleep to come, I heard the camper door open and someone come in. I didn't open my eyes assuming it was my sister's boyfriend that had forgotten something inside. I heard the footsteps walk to the end of the camper, back again, and then the door opened and closed. It sounded like a man wearing heavy boots. I fell asleep and didn't think much more about it.

In the morning I asked both my sister and her boyfriend what they had forgotten in the camper the night before. They both looked at me blankly and said that they both had gone right to sleep after turning in. I asked them if they were sure and they both said yes, they were sure. My husband is also the type that will fall asleep within 10 seconds of closing his eyes so he didn't hear it either. So if everyone was asleep than who or what had walked through the camper? Could it have been the ghost of a miner that was checking us out? I have no idea. I do know that I was completely awake and I had not been drinking.

Thoughts? Another thing was that this 'person' did not turn on any lights. It was pitch black in there. They also walked in and walked out. I was expecting to hear a bag unzip but it was only the footsteps.

I've attached a picture of Bisbee. The town is literally carved into the hillside. If you look across to the mountain, there is a cave in the wall. Although you can't really see it, the campground and Queen Mine entrance is located to the lower left of that mountain.
