I attended a planetarium show at the Griffith Observatory in Los Angeles and was surprised to find that my cell phone service both inside and outside of the facility was very marginal. I have Sprint and immediately after walking into the entrance I was able to make calls with one to two bars. On the other hand, inside of the planetarium, I did not have any signal. I phone was set to automatic roaming and I did not roam. It is a Blackberry and therefore it is not possible to "force roaming" to test if there was a Verizon signal. Outside of the planetarium while looking down at the city, the signal on Sprint was very marginal. Are there a lot of NIMBYs in the Griffith Park area that are anti-cellphone? Why doesn't Sprint and apparently Verizon have a good usable signal in and around the observatory?
