I agree that you could draw a similar sized triangle over nearly every part of the ocean and find a similar number of shipwrecks, plane accidents... so it's not the Bermuda Triangle I believe in as much as:
That anomalies I do believe CAN occur on earth, and perhaps the Bermuda Triangle has one. Something that interferes with the magnetism in that area... who knows? Maybe a very high concentration of magnetic elements buried in the earth or beneath the ocean floor that sends avionics into a frenzy. That seems quite reasonable to me.
