Tempers are flaring along state Route 67 at Poway Road, where a line of cars is backed up as far as the eye can see. Ramona residents are being denied re-entry to the community. Around noon, 100 or so residents got so impatient with the roadblock that they ran to their cars and blew past CHP authorities. CHP called in extra help, and about 10 armed members of the National Guard are now stationed there, said CHP spokesman Brian Pennings.
