#34 is getting right on track. The font is still not quite right. It seems kind of cowboy/western looking. Maybe more a san serif font. Love the blue sky background and it does look great with the orange. Only thing is that it looks like the backhoe has windows because of the black. All our backhoes are all open - could you maybe try putting the blue sky through the windows to see if it will make more like an open window backhoe?
Also, any chance of also seeing this same logo with a white background in addition to the black? We would want to have it on white and black t-shirts and wondering if it will look good on the white too.
