Vishions smoke shop puts triangle signs on the corner of El Cajon and 58th street and it blocks the view to see oncoming traffic on the right side when at that intersection. It's dangerous and we have had crashes at this intersection multiple times. It's bad here bc with the parking lot on the left side and then these signs on the right it is very hard to see the heavy traffic coming from either side. Asked them to stop putting them so close to the corner and they have not stopped. Would appreciate if this not be allowed.
