Just spent half hour wrestling with credit card automated system trying to tell them that I will be in York PA next week but will be dealing with vendors from NY, NH, Indiana, Ohio, Maryland, DC, etc. What a nightmare! But got to do it and I eventually succeeded, but only after saying 'fraud' which got the system's attention. In the past, I have had my card blocked at York because although I told the credit card company I would be in PA, I failed to tell them vendors came from elsewhere.
If you plan to use your credit card to buy toy trains at York, you may want to go thru this pain now rather than risking having the hassle during the show.
See everyone in the Orange Hall!
