Not all of us have the $$$$ to get some sort of fancy ladder rack.
Can you afford an inappropiate ladder rack, is a more pressing question.
What's next..I couldn't afford some gloves/PPE now I can't work (because I'm in the hospital).
Securing your tools properly is equally as important as selecting your tools. What good is a ladder that has been smashed into a million pieces? You can't work off toothpicks
My ladders are secured using "aircraft cable" with loops crimped (hi-dented) on to them, and locks. It ain't pretty, but it is cheap - and extremely secure (even in high crime areas).
sierra's story reminds me of an encounter I had with a box spring....some yahoo had several mattresses and box springs tied to the roof of his van...and flew past me (on an interstate)...I watched him go over one hill...as I crested the next hill - bedding EVERYWHERE. I avoided a few items, but rather than hit a car in another lane I plowed through one box spring. At least he had some wood for a fire that night as he slept on a cold hard floor
