Miami Florida seems like a good one and not too far.

Go to Stuart Florida its beautiful and great for spotting! Trust me, I live there :)

Denver Colorado in the Cherry Creek and Cherry Hills Area. I will gurantee that you will see at least 4-5 worthy exotics on a saturday at cherry creek mall valet. You will see 3-4 SLS's Many GT-R's and a couple ferraris on a saturday night. Maybe even An LFA if you are lucky.

You forgot to mention the possibility of seeing a Veyron. There is also a chance of seeing a McLaren MP4-12C Spider (Vettesrule76 has a photo of it and both of us saw it in the distance once but never could find it.) Bentleys, Aston Martins, & Maseratis (besides GTRs) can be seen almost every Saturday.

Absolutely, I have seen the veyron about a year ago but not since then. I look for the MP4 everytime i go to those areas but i never find it. Bentleys are everywhere and Astons are too. I see about 3 GT-R's everytime i go to park meadows or cherry creek. Many Evoras in the CC area also. If you like teslas just drive by the maintenance center and i gurantee that you will see at least 10 just sitting in the lot. If you have heard of a place called GLOBAL COLLISION then go to it and you can see exotics almost daily in the garage and in the lot. They do body work on them and i have seen an FF, Testarossa, LIME GREEN Evora, Many teslas, and AMG's

CHICAGO! I was just there and its amazing, go Downtown and also if you pass by Oak Lawn many of the people that live there own exotics. On my first day a saw a gallardo spyder, scuderia, GTR, and an aston.

DENVER IS AMAZING. The mountains and parks are beautiful and downtown is filled with exotics on saturdays. The weather this summer is amazing and you could do so many things.

I JUST REALISED YOU LIVE IN COLORADO AFTER I WROTE THIS POST!!!

In Lake Garda there are a lot of exotics, and in Jesolo 50-60 exotics a day. Then Paris.

P.S I live in Colorado, and I have never seen a exotic in cherry creek, but once again, it was snowy out side, during the Denver International Autoshow, I will go up there soon on a saturday.

Uptown Dallas, Texas (full of Bentley, Porsches, and Ferraris)
Vancouver, UBC (Saw at least 20 exotics per day last time I went there)
Denver, Colorado.

Of the places I've been:
Monaco: As good as it looks....enough said.
Miami: Filthy...filthy rich. Bal Harbour is like Casino square...only with more exotics.
Denver: Only place I've spotted a Veyron, so pretty darn good.
Chicago: Rush and Trump tower are very nice....unlike the security in Trump tower.

As for Indiana...well....don't count on anything but there's quite a few Continentals and Quattroportes.

How many Veyron's have you seen Matt?
