OMAHA — Several Omaha residents are against the proposed installation of an AT&T cell tower disguised as a pine tree. The 92-foot tower would be placed at the main entrance to Omaha’s Memorial Park, according to the plan proposed by the cellphone provider and Brownell Talbot School. The tower would sit between the private school’s parking lot and the park. …Nearby trees are much shorter than the proposed camouflaged tower, said several neighbors. “It’s hard to see that a fake tree is going to fool anybody,” said resident Matt Johnson. “I understand why they want to put a cell tower there. But I don’t think it’s the right fix for the city, the park or the neighborhood.”
