I just heard about your hovercraft today, so it may be late notice for you to bring it to the Brighton races I am attending this weekend. I am interested and would like to speak to you about the hovercraft. My phone number is 815-914-3541, my name is Jim Pendergrass. I look forward to hearing from you.
