Hmmm, here's a better idea for 'ya-- since the VX is capable of holding four(4) persons, you could drive the VX (passenger #1) and transport your wife (passenger #2), your own mother (passenger #3), and your mother-in-law (passenger #4) all to MOAB 2011 in the VX on the regular scheduled dates. Take them all up "Hells Revenge" for a picnic at the summit.
In this way; the pre-scheduled dates for MOAB 2011 won't be changed to conflict with other competing groups, and you can have a 3-way Mother's Day celebration all at the same time. Brilliant!!!
