For about 3 years now, summer brings biting flies to the last block of Pier Avenue. I go there every day with my dog and my ankles are covered with welts from insect bites. They look like regular house flies, but they bite like mosquitoes. Because I tend to hang out with my dog (Sasquatch), people talk to me and a lot of tourists have complained about the flies. Even the bartenders, waitresses, have mentioned how bad they are. If you can't sit outside, the park benches and eating establishments are severely impacted. This is a tourist area. Not to mention us locals can't enjoy it. I'm not sure the cause or cost, but it's a major issue. I can't patronize the shops there unless I get food to go or eat inside or go late at night.
