Soaring safaris

OK, it's the time of year to talk about soaring instead of doing it
here in the Northeast, so I'll ask this question. If a person was just
bursting to go soaring this time of year or up to the early spring,
maybe get some XC or badge legs, where would be the ideal place to go?
If it's not all the way on the other side of the country, I could take
my Jantar, or I could rent a glider if it's too far. The chance to get
diamond altitude would be nice.

Thanks in advance for a lot of advice,
Ed
