Things to do in Dallas?

[LSLGuy]

Here is a thread from two weeks ago on what to do in Dallas:

What to do with (most of) a day in Dallas?

I have to go to Dallas for a work conference at the start of May. I have most of a day before the conference(I arrive 11am ish, don’t have any work stuff until the evening). What should I see? Is it worth renting a car, rather than uber-ing to a couple of breweries/BBQs and maybe a museum? FWIW my hotel is in the Design District, whatever that means. Is any of the outdoor stuff that can be reached in like 60-90mins drive worth the effort of renting a car?
