"Let" might not be the right word haha. My girlfriend has been in the outdoors with me on two occasions, both of which where less than fun and one ended up with me almost being arrested.....my friends got me in a lot of trouble and it was nothing with her but she wouldnt stop giving me this attitude.......but anyways she doesnt know what to do out there but if SHE DID then I would feel just fine with her being out there alone. The wilderness has all sorts of fun that sometimes needs to be gone at alone.

If it is a matter of not having someone to go with there are a few websites that offer meetup services for individuals looking for a group or maybe just one or two people to go out and hike with.
