I knew it was BS along..... But! I have seen an 6ft'er posibly longer in Guthrie Oklahoma and it scared the F'ing S%^t out of me me when I was 10 years old. I remember it too this day. That snake still send chills up my spine! On this note.... Anything could be possible I guess...... But, not not a 15' foot'er...That's just stupid!
