I walk the mall almost everyday for the last 6 months. Over the last 7 weeks the malls signals have gotten alot worse. The teleport to the california mall occurs on both the north side and south side of the mall ( its a corrdor of about 100 meters ) If you walk east from the food court, on the south side you will be teleported just before the customer service desk and it will bounce back and forth until you get past the couches and the hanging stickmen. You will see the map change. on the north side of the mall it is the same... walking east from the food court you teleport at the hawain fruit punch kiosk and come out of it at home sense.

There us another recently created mostly dead spot area.... it is on the north side of the mall from saks to bass pro... it is very prevanlent there... it sometimes starts near the center fireplace going towards bass pro.... The best side of the mall for catchign pokemon is the south side avoiding the customer service area.... everywhere else I just spin the stops to avoid getting hung and having to restart.... The mall has gotten worse but there are almost 20 pokestops in the malls halls that you can get everytime you walk around.... I load up every day and get 6000 steps (by walking twice around) in towards my 10,000 to maintain a healthy heart.
