I’m including !hypotheticalsituations in a game I play with myself sometimes. The bolded parameters were all assigned using a random number generator.
Don’t worry about how you were convinced of it, but you know for certain that you will be transported to 17 August 1888 in exactly one week from right now. This is a one-way trip.
Luckily, you will be able to bring some things with you. You will be able to bring back 2 m3/72 ft3 worth of stuff. For reference, that’s about what can be stored in the bed of a standard pickup without going over the bedrails. Let’s say that you’ve been provided the appropriate number of steamer trunks to fill.
What are you going to do for the next week, what are you bringing back with you, and what will you do once you arrive?
You may bring people/pets back with you, but you must subtract their approximate dimensions from your baggage allotment. You will arrive in 1888 in the same geographic location that you’re in next week.
I know a good amount about food safety in the back country. Assuming you’re far from the tropics (northern US qualifies, southern doesn’t) and far from a factory spewing out mercury or something, just boil your water. You’ll be fine that way. Environmental microbes haven’t changed too much as far as anyone knows, so it’s just a matter of avoiding unhygenic things and practices.
