So, i discovered how fun and amazing black friday is last year, but i have a concern this year. last year, i stood in line for best buy from 3am to 5am(opening), and we were realllly far back. this year, were getting in line around 12am, so we should be in good shape. only concern, are we allowed to leave the line as long as someone else is holding you spot? ill be with my dad, so he will be there, but ill need to put the chairs and stuff away. help?
