Licenses: a mere privilege to enter another’s land for some delineated purpose; not a property interest; freely revocable unless coupled

with an interest; no writing required (not subject to statute of frauds); anytime an easement is attempted but fails due to statute of

frauds, a license is created and if money is spent in furtherance of the oral license then it becomes irrevocable and is treated like an

easement (very similar to easement by estoppel)
