I propose if the crossing is not closed .........
No day trips to n/c (run and advertised by gcs)
all people crossing to declare all cash (as was when you left s/c years ago)
no goods to cross either way
jcc to name and shame any one spending more than 100 euros in n/c
no carpet baggers allowed to fly into s/c then cross to their homes in n/c
then no more agruements ............or withdraw from the eu.........
