Time Travel is an interesting subject, especially for a TV show. The 60's are an interesting time period, do you have a favorite episode from the show, and who do you like better Jake or Al?
I liked to Al figured out everything and came up with the plan.  I liked that Jake did the follow through when Al was dying.
Jake was always good about following through. He tried to make a difference.
The ending was so sad...  all that effort and it turned out to ruin the future.
Time travel is tough like that. You do not know if the changes you are making will make the future more positive or not. It was sad that it ruined the future. If you could travel back in time, what year would you travel back to?
I would travel back several hundred years.  It would be scary.  You'd have to plan a lot ahead of time so that you could minimally fit in.
That's for sure, you would need to know the language at the time, the local dialect, make sure you aren't going back into a war etc. 
As a female, it would be scary.  Females have so many "privileges" now that we didn't have even in 1963!
Yes, I could imagine a female going back a couple hundred years would have significantly less freedom then what they do now. History was not kind to females and luckily we live in a time period that is more equal, while still not fully equal unfortunately it is significantly better than the past.
It would be difficult for the people of the time to accept you.  Jake was lucky that Al made him identification.  
The ID did help him. The task of stopping JFK's assassination was already hard enough so having some extra tools to help was key.
