Funny (and GREAT) shot with the dude proposing! LOL
My husband and I also get some odd behaviour and strange looks. The funny thing is, if it's ME with the camera and tripod we get strangers asking what we're doing, that kind of thing, but are generally friendly. If it's HIM, lookout! Apparently a man with a camera and tripod (sometimes) is almost always the nefarious, up-to-no-good type zooming in where he shouldn't be zooming

We've encountered this at our daughter's dance recitals, soccer games, with our kids playing outdoors...the only place it doesn't seem to bother anyone is hockey practice...go figure

If anyone has some advice or similar experience, I'd love to know we're not alone
