1. Don't worry about the truncated file.  It's only 67 lines long and  
ECJ is expecting to build a 100x100 grid out of it.  The trail is  
correct -- it's only in the top-left corner of the 100x100 space.   
See P. 157 of Koza's Genetic Programming for an illustration.

2. You should expect the Los Altos Hills trail to be much *much* more  
difficult than the standard Santa Fe trail.

3. Trivia of the day: I believe the Los Altos Hills is where John  
Koza's house is.
