I was riding thru Phoenix the other day to go look at a new triplex mower at Toro in Goodyear which meant I had to take I-17, just before I get to it I see a sign saying I-17 rough road I didn't think to much about it tell I got there doing about 65 in heavy traffic well it wasen't rough they had gouged the road getting ready to reasphalt it. Wow I hung on tight for 4.5 miles, these groved roads are like riding on marbles around corners, now why wouldn't they put a sign up saying groved roads? I have new Metzlers and it was still a bear keeping it in my lane and I was a nervous wreck after 4.5 miles, needless to say I took another route home it was about 40 miles out of my way but well worth it in my book. I'm really glad I was by myself without the wife on the back with me. Just beware these roads under construction are a nightmare and could cause a wreck very easily especially in the corners.
