Hi all! Will be in PV for the first time ever in May. Are there any excursions that we should avoid because of the season (i.e.: will we be toasting if we go for a horseback ride in Sierre Madre?) I noticed that a lot of the excursions (Sierra Madre, Yelapa, etc.) make reference to a \"waterfall\" or \"river\" destination - given that May is at the end of a long dry season, will there be any water to go to - or is it all dried up waiting for the rains to fall? Any other hints/tips for this time of year would be greatly appreciated. Thanks so much!
