Let's be last minute and attend check out the music in Gateway Park in North Tonawanda right along the water. I've never been here before but it sounds like a great place to hang out and catch some tunes. The music runs from 6-10pm and they have 2 bands: Maniacs (6pm) and then Beatle Magic (8pm). Beatle Magic starts at 8pm but let's meet a little earlier so we can find each other, etc.
For GPS address use 75 Sweeney Street, North Tonawanda.
