me and my friend Chris (publicenemy_14) are building a drop in. we planned it all out tonight, and drew diagrams and shit, and actually used math to help us. it is going to be 5 feet tall, and will feature a ladder, and a drop that is 56 degrees to teh ground. we also plan on making it semi collapsable. is that too steep? ill get the pics we drew up for it uploaded sometime tomorrow. any tips for making it weather proof?
