Not a fun ride to work. Traveling west on a four lane divided highway. In the left lane behind a pickup truck doing 60 indicated. Another pickup shoots across the eastbound lanes and into the merge lane for heading west. Does he wait to merge? Of course not. Pulls right in front of the truck in front of me who slams his brakes on. I get on my brakes hard and start going sideways. I let off the brakes and it begins to straighten up but is wobbling fiercely. I'm heading off to the left and will miss the truck but know I'm about to go down. I regain control a split second before I hit the curb of the median. That bounces me into the eastbound lane and fortunately no head-on traffic coming. I get it stopped and down shift until I get back in first. I get out of the lane and into the median. I should have taken a few minutes to collect myself. When there was a break in westbound traffic I started coming off the median. I went over the curb at too much of an angle and dropped the bike. By that time traffic was upon me. The lead vehicle (another truck) stopped, let me get the bike up, and back on the road. I'll look the bike over later. I think if there's any damage it would be from hitting the curb as that was quite a jolt.
