Alfredo Burdio is a 92-year-old geologist with a great love of the Grand Canyon. The first time he visited it was with his late wife, so the national park is very close to his heart. On October 14 alongside his son-in-law, he will attempt a Guinness World Record by becoming the oldest person to hike the Grand Canyon rim to rim.  #GrandCanyon #GrandCanyonNationalPark #UpliftingArizona #GuinnessWorldRecord #hiking #Arizona #ABC15 __________________   ABC15 Arizona in Phoenix is your source for local breaking news, in-depth investigations, the latest weather and traffic, and continuous live video.   Subscribe to the ABC15 YouTube channel: bit.ly/3zqfyF0   Watch 24/7 ABC15 live coverage here: abc15.com/live   Download the ABC15 app: abc15.com/apps   Watch more ABC15 on YouTube: Latest ABC15 investigations: bit.ly/3NjEEed Uplifting Arizona-Good news in Arizona: bit.ly/3U8RqhM Your Voice Your Vote-Full Arizona election coverage: bit.ly...
