Riverstone is demonstrating why there is no place like home during its 15th Anniversary Celebration with model tours and the chance to win the ultimate staycation. On tour are 19 community models, including several priced at more than $1 million. During the event, the public can register to win a staycation that bundles $2,000 in personal chef services, $1,000 toward housekeeping, a $500 spa gift certificate and a $1,500 shopping spree. Homes in Riverstone are priced from the $300,000s. Maps of the models are available at the Riverstone Information Center, 4855 Riverstone Boulevard. For details, visit the website.
