Alberto Parreira, a lobsterman, contracted in writing to sell Sam Adams 1,000 pounds of fresh lobsters at a particular price during the following season. A few months later, when lobsters became plentiful and the price went down, Adams tried to get out of the contract. He argued that the contract was not enforceable because the lobsters had not yet been caught when the contract was made. Do you agree with Adams? Why or why not?
