Not really, I've always been a pretty independent person. When it comes to my longer trips, I spend months planning it to make sure I get it right (my hubby says that my Google-linked, color-coded itinerary is the most OCD thing he's ever seen). When I'm by myself, I make it a point to not do anything stupid and save those fun, stupid things for when I have an experienced adventure buddy around to help save me. Yes, this means that I may have to pass on a few things that I would love to do, but I'd rather make it home alive.
I select lodging and campsites carefully (Google reviews rarely lie) and use the satellite view on Google maps to look at the parking lot and surrounding neighborhood. If I'm going to have a lot of gear in the back of my truck, I make sure the parking lot isn't visible from main roads. I also usually don't stay in the same place for more than one night, so no one is going to be able to sit around and scope out my routine. I always have a very detailed plan that I give to my husband and my mom, and I check in with them if any part of the plan changes. I use a Garmin inReach that tracks my location via satellite and has an SOS button that will send emergency services to my exact location if I push it, regardless of whether or not I have cell service. Hubby and Mom can look at the satellite tracking at any time to find me and can text me directly on the inReach, so there's always a way to communicate.
Although I prefer complete solitude on the trail, I stick to somewhat travelled trails on my solo adventures just to make sure I'm not totally isolated if something happens. I'm much more likely to encounter creepy people in populated areas and hiking trails tend to be occupied by people with the same mindset as me, so I'll stick to the wilderness any day. I also always carry bear spray. If it works on a bear, it'll work on anything, and it's completely legal in Canada whereas regular pepper spray isn't.
