Hiking alone ain't so bad. I'll bet if a poll were taken on this forum, we'd find that most of us do our hiking solo.
The problem is always matching schedules and skill levels. 90% of my backpacking is solo and the other 10% requires twice the planning and prep. So...don't let not having a partner/group slow you down. Get out there and you'll eventually meet folks that share your passion.

Oddly, I won't go on trips with more than a total of 4 folks, unless it's a scout or church thing.
