Rx construction fair

[flexintex]

Ive seen YouTube videos of expos or fairs where there is a giant gathering of people and they do a big exhibit to build/dig etc... They are always overseas though. Do they ever do those in the USA? I live in Dallas, TX. I was hoping our giant metroplex would have some kind off fair that I could see these diggers in action. I'd love to buy an excavator but I'm always Leary as to how big something is or it's build quality. And being new, it would be a super way to learn tons. I know and have done rc cars/trucks for years. Both electric and nitro. Watching all the YouTube videos I think it looks like a ton of fun.
