greetings from kent also!!I rode n tues to Lake Easton and encountered those grooves for about 1/2 mile.I also slowed down to 40-45 and rode it out..this gives you some area of speed up if necessary with lots of power if in trouble.Coming back thurs pm I encountered the same 2+ miles of groove that you rode thru.I again used the same tecnique..not everyone will agree that slowing down is acceptable but I always ride in my comfort zone..the signs do say use extreme caution...not maintain and pray!!
