Thank you for the friendly and positive responses to my first posting here.
I have bought for our family - Christmas present

A metal detector and been out once over the holiday. No great luck but did not really expect it on the first outing. Managed to load my boots with about a 2 kilos of mud walking along the edge of a farmers field and that's about it.
I am just wondering if there are any specific places near Munich I could try. I noticed mention of a Roman road near Munich but have no idea where it is.
Are there any maps to obtain which show places of interest (similar to the UK Ordnance Survey maps)?
I live in the South East of Munich near Ottobrunn and it would be good if there was somewhere near here that I could start with before venturing too far.
