Fremont is fun. Tightly packed casinos. You can start at one end (personally, playing DD, I would start and stop at the plaza. :) ) and walk down one side of the street, weaving in and out of each casino along the way. If you have not been there it is hard to describe, but imagine a long city street with lots of the old "5 and 10 or dime stores" on both sides. Except each one of these "stores" is a casino. 3-4 per city block.
I stayed there a week this summer and mainly played DD at the Plaza and SD at Binion's (RO6, sometimes RO7) with $5 mins available at all times that I looked.
You also find lots of "pockets" in Reno, but with far more SD games (not mostly crapjack games either). Just watch the big spreads.
One other decent spot is the south strip. On the four corners of LV Blvd, you can hit the MGM, Across the street to NYNY, across the street to excaliber/luxor/etc, and across the street to the tropicana and another I don't remember the name of. You can actually walk all the way up to Caesar's, but it is a hike, and there are some decent stops along the way.
But there is just something "cool" about Fremont. The street has no traffic (blocked off for several blocks) with the light show overhead, people milling around in the street, usually a live band or two performing on stages, etc... Just way cool...
