the two first images with logos are suggestions, and the last one are logos that i like, i think all the logos in this page actually could work. no 1 is my favorite, then no 2 and so on.. no 6 is modified versions for logo no 1 to work in a very small size.  know you liked the red, but are afraid that it can be mixed with the canadian flag or a fire station. feel that the blue are more in line with communicating the right message. best, rasmus
