'Also unlike the real world, you can dig at local parks without breaking the law or damaging property. but if you bought a full sized excavator, you would need a heavy equipment operators license and you cannot dig at a local park. also this hobby is much safer than real heavy equipment operating.'

Thanks, this is great info. Yet more reasons to invest in a scale model excavator rather than a full scale machine.
