Yeah, waiting a couple of more weeks would be good...
Right now I'm getting 3-5 of these a day, and they go straight into my "deal with later" and "Much later" Outlook folders--unless they're very clearly from someone with a close tie to our program or city. So, at this point, reserve these requests for your "must see" programs and let us know why you're so very definitely interested in us. Otherwise it's probably not actually helping you so much.
Oh, also, if you're sending out a bunch of these all at once--when you paste in my name, or the program name, or our city, you may want to proofread before you hit "Send", and make sure the font matches the rest of the email. Because if you don't, well, it might look like you're desperately sending these out randomly...
