Dustin,

For future reference, could you please refer all rails related questions 
to the rails forum.

@blocks is not the type you think it is, I am taking a wild stab here 
but 91 is the ascii code for "[" so  I believe @blocks is a string:

irb(main):007:0> @blocks = "['journal', 'about']"
=> "['journal', 'about']"
irb(main):008:0> @blocks[0]
=> 91
irb(main):009:0>

hope this helps
