I was driving east on i-70 approaching exit 23 when i spotted what appeared to be a bright trail of light in the sky. at first i thought that it was a meteor but then i noticed that the object was flashing off and on as the object continued to travel very quickly toward the south before leaving my windshield's field of view. for me the observation of the object lasted maybe a second or two. my brother was in the passenger seat and he also saw the object. he was able to observe the object as it continued very quickly toward the south. according to him the object was flashing light at random intervals until it disappeared from sight within a few seconds. it happened very quickly and so unexpectedly that i'm sure some of the details that i'm relating are approximations at best. it did happen late at night very close to an interstate exit with at least one good sized truck stop, so i'm hoping that someone else witnessed it and will hopefully report the incident here. i looked up the location on google maps when i arrived home about an hour later. i took the liberty of giving three of the larger businesses there 5 stars and instead of writing a review i asked if anyone witnessed a ufo for the same date and time. hopefully the folks who own/manage those businesses won't think i'm crazy and might even be able to help corroborate.
