It is exciting, all of the work, the thought and the time. It will soon be all worth it. Just to build something unique and get to Bonneville is an accomplishment. Many think and dream, but few actually do it. The first rookie passes are the best and then when you are ready to let the horses run it will make everything worth while.
May I suggest you get someone to take a lot of photos.... As the driver, tuner and everything else you will be surprised how fast the days go by. I gave RAY the RAT a few bucks and he took some fantastic photos for me. If you don't have a GoPro, please go on eBay and buy a used Hero2 there can be had for around $50. If not PM me your address and I'll loan you mine with some mounts. The videos are priceless when you get back home.
My 2 cents,
