If you mention to most people the idea of a woman meeting two strangers off the net they would start to get twitchy, mention it's to go camping, and the twitches become expressions of shock. I agree there is some risk in it. But I also think that this risk may be disproportionately viewed, due to exposure bias. This of course doesn't mean that precautions shouldn't be taken to mitigate some of the risk. I let a friend know where I was going, who I was meeting, what the plan was. I had my phone relaying a buddy beacon (which my friend quickly nicknamed a body beacon), so that people knew where I was. When I got in the strangers car, I made a record of the registration number where my friend would be able to find it if a search was needed. I sent regular text messages updating what was going on (subtext, "I'm still alive"). Right upto the point of "I'm on the train home". The reasonable measures I could take. Maybe I could have been more paranoid? But I was happy I was taking an acceptable risk.
