Alright, just bought my second Goose! My first one was a 79 Team Mongoose, 300 bucks. Wish I had that bad boy now, they've gone up quite a bit since then. Pics coming shortly.
Here's my 2006 (I think?) Mongoose Hardball when I got it.
And here it is not long before I stupidly sold it for next to nothing (fitted Avid Code's and had the frame replaced due to a crack after this photo was taken)
no real damage would have been done unless ridden really hard, because the crown woulda hit the lower arch, amd it would be noticable, so dont worry about it too much, if you are
