Hmm, have thought about this but haven't tried it yet.
Let's see, how would it be to have my feet get even more swollen and have to pee all of the time? I've also heard that being pregnant during the hot summer months pretty much blows. Morning sickness on the playa could be fun. Remember leave no trace.
So, yeah, when I get preggers, I may have to kiss the playa goodbye for awhile.
Be the change you seek in the world.
