We are driving from Indianapolis to San Diego in early June. We are taking I-70 all the way to I-15, so not taking back roads. We already have planned where we are stopping to stay. We are stopping to stay in Kansas City (1 night), Denver (2 nights), Vegas (3 nights), and then San Diego (2 nights). Will be flying back from San Diego to Indy, so no return road trip. Therefore, please don't suggest alternate routes because it is too late to change. It is I-70 all the way until I-15.
Are there any places (restaurants, touristy stuff, etc) that we should try to see along the way?
Are there any things that we should do/see in the cities we are stopping (Kansas City/Denver/San Diego)? We've been to Vegas before, so we know what we're doing there. Keep in mind we are 28 years old, and we will be wanting to try different bars, breweries, etc.
Any advice or suggestions would be greatly appreciated. Please don't suggest things that will take us off I-70 that far, because we will need to drive around 8 hours a day.
