Thats kind of a hard one to answer,
I have also been there many times over the 4th, please let us know where your staying,
or more so, where you will be on the 4th. If your staying DT the only place I have found
is on the top floor parking garage at the El.Co. Or if you can somehow get to a open parking
garage on the strip and park on top, BUT you kind of need to know where they are sending
off the fireworks in that vacinity, and maybe some people will park there cars up on these ramps
early, in anticipation of this, maybe you could elevator to a top parking garage lot and looksee
from there. Hope this helps and I hope more people can give you a better answer.
