Orange sphere about 100' across moving on Susquehanna Rd. just above the trees.

My best friend & I were heading down Meeting House Rd. to my girl friends house (now my wife for 37yrs) when I spotted this orange sphere that looked like it was traveling down Susquehanna Rd. (about 1/2 to 3/4 of a mile away) at about 30 to 40 mhp. It was very large maybe a 100 feet across. I could only see about two thirds of it as it was partially blocked by 40 to 60 foot trees. I could also see trees behind the object.
I stopped my car and watched it for a few minutes and the decided to go after it. I had a 427 Chevy Impala Super Sport at the time and drove down a side road at almost 100 mph to catch it on Susquehanna Rd. but we lost site of it in the trees and by the time we got there it was gone, nowhere to be found. 
We drove around the area trying to spot it again to no avail. I am now 56 years old and never reported it as some people think your nuts. I am not 100% sure of the date or year but I know it was 1968 or 69.
Was any other reports made of this type & Date. I would really like to know if anyone else saw this.
Witness indicates that the date of the incident is approximate.  PD
