at least insofar as I know. The quaint custom of turning old chips into sidewalk-bottoms seems to have passed. But for those who live in Las Vegas, feel free to examine all new concrete pourings around town.
"Honest, I think I dropped my Rolex down there. Mind if I stick my hand through your fresh concrete and feel around for it?"

There should be enough "house chips" from Hooters to supply collectors for awhile, as I've seen them in bargain boxes and dealers' albums for years. But the limited edition chips with the "Girls" may become a bit more scarce to find. So many girls! I for one never bothered to collect any of them, what with 12 girls a year for a couple of years.
