There is a MARATHON SHOWING ALL EPISODES OF THE WALKING DEAD (seasons 1 and 2) from July 7th to 8th. To make sure you dont miss all of the episodes, make sure you record them. They will air from 11:30 AM on Saturday July 7th to around 10:00 PM on Sunday July 8th on AMC.
If you missed some episodes of the show, or you would like to start watching (highly recommended) you probably want to record the shows from AMC. If you have any questions, please leave a comment. I will respond.
Also, Netflix airs season 1 on its online streaming selection.
