Tried to go to Radnor Lake earlier today and the east lot (off Franklin rd) was completely full and cars were lined up waiting to park. Sat for 30 minutes behind ten other cars before we gave up and left. What is the best day/time to go and are there other places to park? Is it just a matter of getting there early? Park ranger sitting at the entrance said it's common for the lake to be crowded like that in the summer but didn't offer much help.
