Tracy Herbert has been dealing with Type 1 Diabetes for 40 years. When diagnosed in the 1970's, doctors at the time weren't optimistic about her future. Tracy explained that doctors doubted her ability to live past her 20's and ever have children. She did both.

Now, this grandma from Texas is cycling across the country. She began at the Golden Gate Bridge in San Francisco and is on her way to the Brooklyn Bridge in New York.

The trek across I-80 of course, resulted in a big adventure through Wyoming's rugged terrain. Check out some of Tracy's videos as she rides from the Utah border to the Nebraska border!
