Rhea Kain is the sole owner of the land where the El Cosmico lodging is located outside of Yreka. She and the SISKIYOU COUNTY PUBLIC HEALTH & COMMUNITY DEVELOPMENT DEPARTMENT have reached an oral agreement about upgrading the septic system for El Cosmico. This agreement will prevent the county from closing El Cosmico. Rhea has given up driving after getting lost several times and her friends are getting used to her evident dementia. Now the county is unsure if they will "allow" Rhea to sign the document.

1. What is the county's problem, from a contract law perspective?

2. Give me two ways that Rhea and her friends might be able to make the agreement with the county.
