Which would you rather have as a secret base of operations?
Fortress seems much cooler (no pun intended) but poking around the trophy room in the Batcave would be pretty awesome too... plus with the Batcave, I get to take the Batmobile out into the city streets. Then again, Kryptonian tech in the Fortress might be more exciting, and certainly safer than Gotham... Fortress of Solitude for me.
well considering the fortress could be rebuilt anywhere using the sunstone or tesseract technology it doesn't have to be in the artic. Could plant down somewhere nice and warm like an ocean side mountain cliff in Hawaii. Batcave has to stay in Gotham.
