Highly unlikely that we'll be able to make it just because of previous commitments and all but sure wish we could. I'll add Discovery Park to the list of places you might consider for a get together as, at least back in the day, it used to be fairly nice. Depending on your agenda you might even get a little "publicity" if you help a gathering in a public area. Personally, I think I'd rather just keep it a permie peeps but I already said I doubt we'll be going so, whatever.
One of the downsides of any park though is the prohibition against "adult beverages" so that may be something to consider. Or not. Just depends on the folks. Also, it may be a little damp this weekend (YEA!!!) which should not be off putting to anyone who is accustomed to the area but it is nice to have shelter just to keep any vittles dry.
Hope y'all have a great time!
