Here are the ground rules, my friends, and no nit-picking ninnies, please. OK some nitpicking but be a good sport and play along.
Three months somewhere in Europe. You cannot return until the time is up, and you will have the option of one 3-month extension.
Any century or location
You will have all of your dental and medical needs addressed prior to departure. You can take medications to sustain you for that time period, such a blood pressure meds, etc., within reason. Keep in mind there may be no electricity.
You can take no food and you will have no ability to communicate with the present. At a specified time and location, you will be transported back to the present. If you miss it, you're screwed until three months later at the same time/location.
A plausible backstory, job training, adequate currency, history lessons, and period clothing will be provided. Your teeth will be discolored if necessary and every other practicable physical change will be made so you can blend in as much as possible. You will arrive in town with a needed skill allowing you some form of employment, which could be banking, cook, servant, buggy whip manufacturing, physician, teacher, attorney, coal mining, street lamp lighter, etc. This would all be negotiated and arranged with the time travel team. Training will last at least six months or until the team director deems you ready to proceed.
OK, so now the time has come to submit three options for your time travel destination. When, where, and why? What occupation have you chosen?
