, WOW, it's good for a thousand years ;)
The way to maximize your time on that visa is to make sure that you exit/re-enter the country just prior to the 17th of Oct.
That will get you the final 60 day entry you could get on that visa and then extend that stamp by 30 days at the immigration office.
That wrings the most time out of the visa as possible.
