I hear ya'.

Sometimes I think TXI (big rock hauler co here) must be paying someone with off.
I travel the same 30 mile path of hwy everyday and have never seen a DPS unit on this same route the rock haulers use. Yet, a mile or two off of it I see 'em on the FM roads all the time. Hmm...

Called in many times to complain about untarped loads, 80+mph passes on the right... never any results. Always the same story, "we just don't have enough resources..."

I just try to stay away from them but its difficult when they blast past you.
