midwest cardrooms, help needed (iowa, nebraska, illinois)

[aggie]

I'll be driving from CT to Nevada and want to stop and play cards along the way. I'm taking I-80 all the way to Denver.

Can anyone reccomend a cardroom with the following:
-bigger action 20-40+limit or 5-5+NL
-proximaty to I-80

Any help would be greatly appreciated...
