The arrival of warm temperatures means the beginning of larger crowds on the Hood River Waterfront.  For the Port of Hood River, that means preparing to deal with the issues that come with those numbers on their recreational sites.  Port Executive Director Kevin Greenwood says hiring maintenance workers has been an issue, but at this point he believes they will be fully staffed for the summer to handle garbage, cleaning restroom facilities, and doing landscaping among other tasks.  Greenwood says parking will continue to be tight, so consider arriving early in the day to visit the waterfront.
