>>Can anybody recommend a good place to get my Boa probed? I live south of Philadelphia and I cannot find anybody that will sex a snake. I have tried a bunch of different techniques to sex her/him and all are inconclusive. If you do the rub down the tail technique then it feels like a male, but if you do the pop test nothing comes out.

Either a vet...downside you pay more 'cause they are gonna charge for a visit. Or contact any local clubs or pet stores....someone must know how in Philly area. I would make sure they are experienced (vet or hobbyist). Other poss. is the White Plains shows. You could check the vendor list and see if someone there would do it for you.
