5.00, reasonable. Well I very much enjoyed my session. I don't remember what flavor I choose. When I sat down, I was tired from all my walking around, over heated,( it was a beautiful warm summer day), and getting grumpy, but i did not want to leave yet, there is always so much to see and do at the fair. At first I felt a little light headed, but as my body adjusted to so much clean oxygen I started to feel the effects. After my 15 minutes was up, I felt great, I was re energized and ready to go some more, all my exhaustion seemed to have melted away. I stayed at the fair another 3 hours. I think I visited nearly every booth there. I don't think I have ever stayed at the PNE for such a long time. After I got home It occurred to me that I should have bought one of your canned oxygen.  I will be back this year, and this time I think I will be looking at buying one of your portable oxygen bar. I hope you guys will be there again this year. Thanks Girls Mrs Greta W I hope everyone will come out and check out our bar at the PNE  again this year. Latasha
