Gravel Roads suck!

Today I had scheduled 3 hours of endurance work planned which included some tempo on the hills...Didn't quite get it all in! 1+ hour on the trainer and 1 hour on the road...Once on the road, I decided to take my normal route to do some tempo up some good climbing hills...But, I noticed an orange sign on the road that said "15 Mphs - gravel road ahead", Great! I decided to attempt it but, was passed by one of Coventry's read-necks in a suburban doing well over 15mphs and kick'in up some stones..decide it wasn't it worth it and changed directions...Got'ta love Coventry...a real diverse cross section of the America and also the only town that uses gravel on the roads! nice!
