I was the only cf'er in my small town back when someone did one while I was in high school.... that was when I found out about Great Strides.
Last year, I tested positive for b. cepecia so my family all went last year though and there were only 2 other cf'ers... a little 4 year old and a 19 year old.
I think that I would be nervous for sure, but you are in the open (with wind and breezes and 3 feet) and as long as you didnt touch other food and such it would be fun, internet is great but to actually see a live CF'er makes it even more real that you are not alone.
I also have the MA and before when it was just m. cholenea I actually attended 2 "informative" conferences put on my old ped doctor here in my college town... knowing what I know now, I would have never went or at least wore a mask... yes we were in a room, w/o masks!! So dumb, I wasnt very educated on CF and was aware of bug transfer but trusted my doc but it doesnt make any sense now. I actually feel guilty, b/c there were little kids there, and I hope an pray to God I didnt not give them anything... so many mistakes. I did try to sit as far away from anyone though... I just didnt know that what the potential I had with my bug.
At Stanford they dont let anywone w/ mrsa or b. cep go or any other drug resistant bacterias... they are more strict w/ cf conferences and such which I would appreciate if I could go.
Oh and I do get bummed though that I cant go to my local GS, last year my sister was the chairman of our town and so I helped get it ready but couldnt really see how it turned out except for pictures. This year i am even more involved but am laying out the course, so I feel like I am contributing in a bigger way.
