A walk in the woods.

I have been handed a dare:
I have to walk 50 Metres through the woods at Fairmile Bottom near Arundel wearing a Baby Doll nightie and panties set and a sign telling anyone I may meet that they can spank me. This is due to happen on Monday 23/06/14 in the late afternoon.

What time is late afternoon?

We'd like to hear how it went. :D

And, how did it go?
