Subject: array1 + array2 newb question

Hey all,

I'm a ruby newbie, so this will be obvious, but I can't figure it out.

I'm trying to create a map grid from arrayed names of streets.  I  
want to go from [1,2,3] and [a,b,c] to [[1,a], [2,a], [3,a],  
[1,b],... [3,c]].

so far the closest I have gotten is

a1.collect!{|x| [x, a2.collect!{|y| y}]}

which returns-- well you can try it if you like, but it's not right.   
Instead of just returning one value of a2 at a time, it returns the  
whole thing every time.  I'm guessing I need to somehow cycle through  
each element of a2 (ie a2[0], a2[1], a2[2]), but I can't figure it out.

You guys will probably eat this up.  What am I so obviously doing wrong?

Mike
