This is not Meetup Event. Aqua Adventures (http://www.aqua-adventures.com/index.php/kayaking/kayak-local-tours/24-evening-kayak-tour) has a regular Thursday evening Social Paddle. They run from May through October. These paddles are generally about four to five miles long and are pretty slow paced and fun with friendly folks.
If you have your own boat this is a free event, if you need to rent one they are $15.00 for the evening. Aqua Adventures has many types of kayaks so this is a good way to try something you've never paddled before.
This paddle should include a sunset and then some darkness so a light is mandatory, for more information go to the Aqua Adventures (http://www.aqua-adventures.com/index.php/kayaking/kayak-local-tours/24-evening-kayak-tour) Web Site.
The paddle starts at 6:00 PM please get there early to get your boat rented and get fitted into it.
