This must be the third hotel 'roof top' tent in San Francisco competing for longevity with the City Permitting Office. Also at the St Regis and Hotel Vitale weekly or monthly time limits are strictly enforced with these architectural alterations to the original building's profile.
Looking up from a recent Potrero Hill morning walk with my dog I spied a gigantic gas powered barbecue with hood on the roof of a nearby house. Nice.
