Fassnight Park

Yup.

You might try the Springfield Park Board's website. Not sure, but it's worth a shot.

Yes they allow dogs but not swimming until the last week they are open

They were, and open during the week until 6:30 p.m.

I dont think it does but i could be wrong

Yes

Springfield, for some stupid reason, has made "hammocking" illegal.

Yes.

Are u guys open tomorrow ??

The Park itself is free to use all open areas including handball courts. The swimming area cost $3 last I heard and that for adult. They do have a canned food donation = ticket for entrance and it was one day per week last year and on a after rush hour swim time but that may have changed this year. Best thing to so is ask about it at the desk when you go or call thw Park Board and follow their prompts...
