College Avenue Between Montezuma and El Cajon. This road requires you to go into a valley and come up the other side. There is a senior center near the bottom of the valley on college avenue that requires reduced speed of 35 mph. Most people go 50+ because they are going downhill. One officer will radar you at the bottom of the hill and the other will pick you up at the top (usually going northbound). Typically the cops are out during a.m. school traffic and at dusk. Also watch out for the photo enforced signal at College and Montezuma.
