The UK is due to leave the European Union on March 2019.
With fears around the future of the border, The Irish News is running a series of articles on the frontier.
Did you live on the border during the Troubles? What are your memories of that time?
Do you remember a pre-Troubles border? What are your memories of how people managed customs posts and other issues at that time? Do you have any photographs?
We will use a selection of your comments in an article therefore we ask that you include your full name and where you are from, although this is not compulsory.
