Well Bill I wont say how fast my log truck would go. I need to point out though that, that night I was PASSED by a fellow hauling "swinging beef". I heard two guys talking on the C.B. about the one driver just getting his tractor back from the shop. ( he had new injectors installed and the computer bypassed) the second driver said he could see that it had made a big difference and would driver #1 PLEASE slow down so he could catch up and they could "run together". To which driver #1 replied,"Now Mikey you know I have rules" I don't slow down for nobody to catch up, but this one time I will back it down to say 115 for 3 miles and if you haven't caught up by then , FORGET IT I'm going to put her back in the big gear. All this time I was laughing to myself thinking, there aint NO WAY a rig will go that fast , let alone a dang FORD AEROSTAR. Well, the joke was on me 'cuz when he went by me it dang near pushed me onto the shoulder, less than 20 seconds later the second one went by me. ( the second truck was a Cat powered freightliner....I asked) I don't know for sure how fast they were going, but was tempted to get out of MY truck to see if I was parked! Their tail lights disappeared in less than a minutes time. I was running on the cruise control at 65 at the time. BTW, after I put the first 250k miles under me in a big truck I made some changes. For one I NEVER drove over 60mph in Mi, especially with double trailers. Also, where the speed limit was 70, I was content to run at that speed. Guess I'm getting older or something?
