I have been informed that the road map icon for a small number of sites was not displaying a road map when requested. Investigation showed that the URL contained a code error where httpss:// was used in place of the correct https:// for some hikes.
This has been corrected for hikes L04, L19, L39, L56, L57, L58F, L59, L60, L61, L62.
The road map now displays properly for these hikes. Apologies for the error.
