That's up to you...what it 100 miles of gas and time worth?
Two hours of driving, plus around $20-$30 gas?
That would be at least $100 to make it worthwhile to me (I'm not in it to make money, I just need a little extra to get me moving, since it is far easier to just make a split!). Sometime the hardest part is being able to walk away when they don't want to pay. I agree, cut the section, throw it in the trailer or truck and take it home. That's still three hours of work/driving.
