Anyone have even a small piece of land in Colorado not in use?

Hello! I study permaculture and love taking care of plants but I have no land currently. I’ve been keeping plants in pots, but I wanted to work with the three sisters. I do a no till method, with homemade soil that uses no animal parts etc. I use to be a landscaper and know how to keep that stuff looking nice. I know this is a stretch but I was wondering if anyone had any abandoned land or anything for me to plant a few corn plants? I would keep it neat and leave no trace the next year. Just let me know, thank you!
