Proposals for a new convention center for Casper are being considered this week. Casper City Council got four respondents to a request for proposal that went out in April. Of those, Mayor Paul Bertoglio says they're interested in two. Both respondents, he says, have local ties and strong hospitality backgrounds. Bertoglio says at this point there are a lot of questions to be answered from both sides, but he indicates they hope to keep the process accelerated, because they're serious about capturing lost business.
