Did you hear Broomfield traffic on Lakewood's sites or just see their ID? I believe TGID is one of the System Assigned IDs (SAID) used for patching on their system.
not sure if it was broomfield I saw TG 65, and other lower numbers maybe thats not Broomfield on that system it is in the Colorado system, all the lakewood and Wheatridge are like 37...
