A light drizzle lasting 1/2 hr or so before heading to the next lawn, and every time I touched the brakes I started to slide. I'm not sure if the trailer brakes and/or the truck brakes were both locking up or not? All of the tires are in excellent to good condition. First stop sign I came to, I almost didn't stop. 25 mph speed limit down the main street went fine at 5 stop signs. Turned left over a bridge over RR tracks, down a steep hill to turn left, right after the bridge, touched the brakes 3 times, tried to turn (not happening). Oh well, we'll hit those lawns Friday. Kept going down, the stop sign at the bottom is maybe 50 yds away and a tractor trailer starts making a right hand turn to climb up this hill towards me. *@!!@@ I have a choice, keep going down with no clue where I may end up or hug the curb, and there's a telephone pole snug to the curb. Lucky, the curb slowed me down and I never touched the pole. The driver of the TT waved thanks. Right behind him, another LCO was making the turn and we met face to face. I said, It's getting slippery, and he said, Was that you I heard? I said yeah, and then he proceeded to spin his wheels up the hill I just came down. The day ended safely again, but it seems there are certain roads that are impossibly dangerous. This isn't the first time I've had this problem on the same roads. I need advice. Thanks.
