Task: Question Answering
Input (English): Context: I had to get a CT Scan yesterday and since I got the day off from work , my mom and I decided to go camping last night . We ' ve been hiking more and more , and talking about getting into backpacking , but this was the first time we actually spent the night in a tent . It was car - camping really , since we were at an official " tent site " at a state park and the car was maybe fifty yards away , but we decided to hike out to one of the backcountry camp sites anyway so that we 'd know whether we could hike out to it next time around . 
Question: What may be the plausible reason we park the car by the campsite ?
Output (English): We were at one of the official “ camp sites ” .
