So she slips into a gully and if she had a cellphone they would find her immediately.
But she leaves her cellphone at home to go on this little walk.
Go figure.
Any way if she was going to be gone for an hour then she can’t be in a gully more than 2 miles away.
That shouldn’t be too hard to find her then.
Some people can’t stand to be without their phones for 5 seconds. Others can’t be bothered with them.
