OatMeal, Great info, thanks. Looked at the cycoactive site and read the data. Sounds like a GPS is a must. Seems odd that the mileage would be so different. Now I'm wondering about the wisdom of riding my Berg on this, but if I have a support vehicle there shouldn't be any problems. Time will tell on exactly how many riders actually show. Again there will be no permit so the numbers will have to be small and/or spread out. My experince has taught me that when the date arrives there are always fewer riders for this type of event thatn have indicated they will be there. Keep in touch and thanks for the information!!
