Interesting topic. I personally tend not to cache alone, but not because I am self-conscience or because I don't feel good without other people there. On the contrary, I rather enjoy caching with just me and the dog more but I am a 16-year-old female. I am basically the perfect target. The area I live in isn't a bad area by any means, but things happen EVERYWHERE now, even fairly populated or frequented areas. Heck, Stoney Creek Metropark, one of the big parks in the area, was where Steven Grant hid his wife's body parts after he murdered her. And this is a VERY populated park! The populated trail system by my house has been home to several rapes. You just never know theses days. My mom is also a rape victim so she is even more paranoid about me caching alone. She doesn't mind if it is in an urban area, but she is definately uncomforatable with me soloing most of the time. And with her past, I understand and respect that. I guess it just depends on your comfort level and the chance you are willing to take. Just remember to let someone know where you are going if you do solo cache, even if it is "just a drive up". I have a dog, a BIG dog, but he is a lab/golden mix. All he'll do is lick someone to death, so a dog isn't nessassarily a safety net, although I do think he would defend me if needed. So solo cache when it is safe, but don't take a risk. That cache, despite what some may think, is NOT worth your life.
