Lyman, I appreciate the difference in rates around the country. I have found the rates here in the Denver area to be higher than the midwest, but had not heard of higher rates in the D.C. area. It costs more when you have to work closely with government, no doubt.
Make no mistake that I do up-charge for extra time and travel, so if someone says "RaceMeasure will do it for ...", remind them that is the base fee, and doesn't include travel, or attending meetings, etc. for clearance from police. I have been fortunate, I suppose, that only one course has required coordinating with security personnel, so my rates pay a good hourly rate. I do pay attention to that.
If anyone feels my posting of rates is a hinderance to their pricing, please let me know, and we will figure out a way to not have you "shopped-down". I don't want to take anyone's negotiation position away from them.
