Backers of a proposed casino at the old greyhound track in Wood Village are collecting signatures at a fast rate and look like they have a good chance of making the November ballot.

Matt Rossman and Bruce Studer, the Lake Oswego businessmen who have pursued the casino project for years, recently began collecting signatures on their latest two petitions — one that amends the constitution to allow a private casino and another that lays out the legal parameters for their project.

By the end of April, they reported that their paid canvassers had collected more than 112,000 signatures for the constitutional measure and nearly 105,000 for the statutory measure.
