Example, young man asked about getting a burm a few weeks ago. Some yahoo came back and told him not to and quoted the average adult size to be 20 feet. I called that out to be total crap and it is. 20í snakes are as rare as henís teeth.
But that misses the F-N point completely. Who cares if the max size is only 19.5 feet. His/her (I didn't read it) point was probably that Burms get too big. Who cares if they were off by a couple feet. Their debate probably wasn't "exact average Burm size". It was probably "this animal is unsuited for you".
