I have a question concerning SPR. It may have been answered already but I couldn't find the answer. Say you are called upon to measure a route in a densly populated area that has houses lining the streets and there are ALWAYS cars on the street. It's not practical to have the cars removed from the street prior to measurement. Also, you can be sure that there will be cars parked up and down the streets on race day. I think I know the answer but I wanted to hear it from the experts. My guess is that you use a straight line as close as possible and parallel with the cars and try to get as close to the curb as possible at turns. Is that correct?
