Hehe, maybe it makes a difference if the thing to be climbed is firmly bolted to ground or not - silos and radio towers tend to be securely rooted, but aluminium ladders can tilt and fall at any moment without advance notice, it's like a lever trap to catch unfortunate DIY builders =)

My house still needs those finishing boards around windows and the door. That will stop wind and rain getting through, and will also make the house look even more finished. I wish I can get that done before the winter hits.
