I have just had this email asking for help with the DoE Silver award. - Can anyone help Emily?

I am looking to start the physical challenge of my DoE Silver Award and wondered if it would be possible to do geocaching for this part? My real concern is that I need an Assessor to sign this off at the end of 6 months and wondered how that would work as it can't be family members. Are you aware of anyone else who has used this activity and how they managed the sign off?

Thanks for any help you can give me.
