Francisco d'Anconia, a recently retired lawyer, joined the 'NO TECH movement in July 2018. The members of the movement are strongly opposed to the use of digital technology. The majority of members live in the village of Shangri La.

Francisco will be moving to Shangri La at the end of 2019. Therefore, he will no longer need his truck, a five-year-old Ford F-150. He places an advertisement on Craigslist.

'FOR SALE'- Ford F-150 in excellent condition. Will be sold to the first person who sends notice in writing that they wish to buy it for $25,000 to the following address: c/oFrancisco d'Anconia, Baker Street, Fresno, California.

On Sunday evening, Hank Reardon, a newly qualified driver, sends a letter stating that he wants to buy Francisco's truck on Wednesday morning.

On Monday morning John Galt, Francisco's acquaintance, reads the ad on Craigslist. He sees the advertisement and recognizes the address. On his arrival at work, he sends Francisco an email to the email address that he provided him with when they first met, two years ago, stating that he is willing to pay $25,000 for the truck. Francisco never receives the email, since as a member of the 'NO TECH' movement he no longer uses computers or mobile phones.

On Tuesday evening Francisco meets his friendRagnar Danneskjldfor dinner and over the course of the meal, Francisco promises to sell the truck to Ragnar for $25,000.

What should Francisco do? Is he contractually bound to Hank Reardon, John Galt and Ragnar Danneskjold? Discuss...why and why not in each case. Give me your opinions based on law experience
