Spring/Summer planning. Help me?

[gargoyle]

I'm wanting to get some more photos (no collection) of some ontario snake species this year and was just wondering if anyone can give me some habitat information on finding a couple in particular (I respect anyone that does not want to give actuall locations, I would prefer just habitat info to protect them). Heres the ones I'm looking for, for this year

Eastern hognose
Eastern milks
*Black rat snake (if possible)
Smooth greens

I've gotten lots of Turtle and garter snake pics over the past few years but never went out specifically for snakes yet. Just thought I'd work on putting a little presentation together if possible (about a four year project I assume) Thanks, and if there are any other interesting species you think I should be looking at for this year let me know! And just to re-iterate my point. Under no circumstances will myself or the person coming with me be collecting or disturbing, just some photos, nothing more.

Thanks,
