While I would not encourage you to leave this forum in this case there is an excellent forum for what you need. Both forums have there strengths. The forum for your interest int he ABQ Balloon Fiesta is the Escapees Discussion Forum
. We went last year with the Escapees Boomer Group and had a ball. We were encouraged to volunteer at the Fiesta with the group (not required) and it completely changed our experience - for the better. The Boomers are there right now and DW is getting daily updates from them and, as usual, they are having a blast.
They stay in the fiesta RV park with several hundred other RVers. No traffic issues as you walk to the events across the street and there is a big empty space among the RVs where some balloons land every day they fly! It is dry camping but for $10 you can get a pump out and fresh water - not from the same truck. We had the service once.
You can join the SKP forum for free and get plenty of info between now and then!
Good luck and let me know if I can help.
