Early to mid October should still be pretty good, depends on how the weather goes as Tattoo said. I'd have alternate dinner plans just in case. Keep an eye on the site here for the reports on where they're getting them. I did pretty good on my last trip of the year on 10/17 http://www.bluecrab.info/forum/index.php/topic,44438.0.html
no too far from there but, I was crabbing by boat. I don't know of any places that rent gear but, hand lines are pretty inexpensive as are ring traps. Good Luck!
