Hi, me and my sister live close to a forest we found... its about half an hour away, Our big sister just came home and we were thinking about showing her, remember she is in her 20s . She said she would love to see it because of her love of nature, but were not so sure about showing her because when it gets dark , lots of mean (seams dangerous) people about, and she might want to stay. We are scared in case she tells our dad not to let us go anymore, but I love it up there,
Should we bring her?

I don't understand. You found a forest, which was probably always there l/2 an hour away and you want to take your visiting sister there, but why would you want to stay till dark? What do you mean, dangerous people? Would that not be a deterent for going there if you plan on being there past daylight?

And you are scared she might tell your dad who will not let you go anymore? I would hope so !

If you don't know the area, then bad idea to go hiking.

I understand your veiws and concerns, by dangerous people a mean like, they would slabber at you walking past, not to dangerous but this place is so beautiful, and were I live that's really rare, but this is a puplic place and at the minute it gets dark at four , my and my other sister would never stay there after dark, but I'm not sure about her...
But thanks for all your help :)

A public (puplic?) place, so not really a forest. Do you mean a park ?

You asked for opinions. I was offering mine. How did that deviate from your question? People who slabber are not sane. Slabber means to do drool and spit.
