If all you had to carry was a keyboard weight wouldn't be such a big deal. It's getting all the other things to a performance that really make setup a chore. I've found the weight of anything is directly proportional to your age. The older you get, the heavier things are. Being an old dude I've had to resort to technology to lighten the load. One of our earlier ancestors invented a thing called the wheel. After listening to some wise people I invested in a case with wheels and found that was a step in the right direction. ON finding the wheel was a handy thing I got a card with 4 wheels. That reduced the number of trips during setup. Now all I have to do is figure out what to do with the cart? I think I need a lighter one!
Have fun!
