Do your due diligence
Give Fortune Valley a pass: it has the worst penetration in the Black Hawk & Central City areas.
Black Hawk is H17, while Central City is S17. But Central City tends toward worse penetration and less tolerance for action above $50. The quality of the games and dealers in Black Hawk is better, although there are dealers all over town who are arithmetically challenged.
Scouting pays off. If you're only in town during a business trip, you won't have the time to find the best opportunities, but CBJN has good enough data to point you in the right direction.
Be nice to the voodoo-worshipping ploppies next to you: sometimes they're dealers in other stores.
No need to hang around any one place, because there's always another one waiting up the road.
Surprisingly for a place at 8500 feet and 45 minutes from Denver, the weeknights are busy. You'll get more play while the sun is up.
I doubt that there are more than a tiny number of advantage players around Black Hawk or Central City. The effect of counters on the bottom line must be effectively nil, seeing as the betting limits are so low and the regular customers are so eager to double their hard 16s instead of their 11s.
