Guess correctly and be crowned "San Lorenzo know-it-all" for the week.
Congratulations to for being the first to correctly guess The cool-looking sun can be found on the back wall of off Hesperian Boulevard. Richard Orput appeared to also correctly guess the location of the sun, however due to ordering of the posted comments (despite technical issues with the site last week), his answer came right after Keith's. Great job, you two!
