G'Day!
About a year ago there was an ad in a local paper for a Bubble .... in Bend, Oregon.... I called and talked to a guy who "was selling" it.... but it had just sold. So, when my husband said I almost bought your Bubble.... we figured there couldn't have been too many in Bend!

But, if you didn't just purchase it, and got it from your folks.... then there is another one out there somewhere....
Interesting side bar, when I spoke to him he said he had so many calls.... (duh, ya' think?) he was really surprised! I called the minute it came out in the paper... and it was gone.... but then I found our Bambi. So, we are happy campers!
