Chronic Logic

U DA MAN!!!!   Thanks.  Its that thinking outside the box thing again.  You might also want to talk about diamonds.  They can be made very ridged so you can span a longer open space with less support.

Not sure if this is the right place to talk about this.....so let me know if its not.  I am totaly stuck on lv15 of the bridge builder demo.  I hope that someone out there has played BB  (i think its an older version than the PFX one).  

Thanks for any help!!
