Whereas we could not all the time notice its influence, it’s an integral a part of our on a regular basis life—from supporting farm operations that lead to meals on our tables to hauling supplies round a job web site constructing our properties and places of work.”
The NIHF yearly acknowledges inventors, promotes creativity and advances the spirit of innovation and entrepreneurship.
