Ah, you're living the dream: working in the summertime, but you get the benefit of picking your office. Instead of being tethered to a dreary desk, pick one of these temporary (i.e., "seasonal") summer jobs that have the added benefit of being remote. Clack poolside or from the woods…anywhere you can get a WiFi signal.
FlexJobs started a list with some possible links to open jobs, so you can start looking quickly. Just don't forget your sunscreen, and you'll be sitting pretty while you're getting some hours in at your temp job.
