I am sure this is asked all the time (and I have seen the FAQ section and the links don't work), but we are heading to Banff July 16-22. It looks like it will be in the low 80's high 70's. We are from Texas where that is amazing shorts weather! :) If we are planning on hikes and outdoor activities, I know we should have layers, but are we talking pants or shorts??? This is very important for girls. :) We figure the nights will be a little chillier, so jeans and light sweaters are on the plan...Any ideas or information would be great!
