Letter: Put new prison, Capitol on same site
It makes more sense to move them both. We will get a better bang for our buck and we can have two new state facilities built at the same time and lower the overall cost. Get the Capitol off the earthquake-prone Wasatch Fault. Heck, the Capitol is older than the prison anyway. Let's get a new one.
And think of how the developers will fight over the Capitol real estate. They can renovate the Capitol into condos/office, or better yet, tear it down and build high-rise units (more units to sell and what a view!).
It would be a bit more of a drive for our legislators, but they only meet a couple of months a year anyway. It will be closer for those found breaking the law to get to their new digs and still be close to their old colleagues.
