I suggest a letter campaign to General Manager Les Vann, WLOS, 110 Technology Drive, Asheville, NC 28804, expressing your interest in ABC's HD programming would help. I have asked for the name of the CEO of broadcast at Sinclair, but have not yet received it. Meanwhile, watch for a posting here. I will also include ABC's affiliate relations address...so save a copies of your letters for later posting.
ps--It is interesting to note that Sinclair has a DT division!
