I think I'll be totally thrilled if our little female B/P hits 5FT. For us, that would be a big snake, and we were looking for the 4.5 to 6FT range, with a nice attitude.
If we get that I'm sure we'll all be happy.
But a 6-8 FT something would be pretty cool I gotta say.
Most male red tail boas stay in the 6-8foot range. A male bigger than that would be very rare
