A good LSAT is not a good reason to go to law school. There is only one good reason. If you can read this sentence below, and it rings true, go to law shool:
“I am genuinely interested in the law and I have a sincere desire to become an attorney and practice law. I have come to this conclusion by thoroughly researching what law school and working as an attorney entails.”

As far as your best option for schools, it really depends on where you want to live/work upon graduation. You don't have the scores for HYS, but a T1 regional school might be a possibility. As for lower tier, it depends on where you are. Your 168 might get you a scholarship offer at a lower-tier school.
You should probably spend some serious time thinking/researching your options.
Good luck, and please let us know what you decide.
