Yeah I was wrong in thinking that load would load local vars. So like  
others have said you will have to wrap your var in a method or class.  
Or you could eval the file by reading the file in and running eval on  
it.

#a.rb
a = [1,2,3,4,5,6]

#b.rb
a_contents = File.open("a.rb"){|f| f.read}
eval a_contents
p a

# => [1, 2, 3, 4, 5]
