For one thing, it's hot. And nobody wants to go hang out in center city in 90 degree heat if they're not used to it.
Bless those who live there. I don't know how they do it.
We had pretty good success getting people out to our 422 ARCH networking event on June 12th, but traffic was a mess and that was in the SUBURBS! I can tell you that's the only networking event I remember attending since June began. (and that was my own event, haha)
Not every group is taking a break like we are at 422 ARCH. The Who'ja networking group has like 3 events scheduled for each week. It's tempting, but at the end of the day I just do not feel like hauling my butt out there. Maybe I have senioritis.
So this summer, I don't know if things will pick up as far as attending more networking events next month. It's hard enough convincing my loving mother in law to come over on a Saturday afternoon for a small party.
Forget trying to gather a big crowd. Be happy with a small gathering until vacation season is over. That's just my two cents.
