* RAPID TRANSIT: Potomac River water levels have remained up this year, which is good news for paddlers. To that end, Mike High of the Canoe Cruisers Association has put together a series of trips on Wednesdays; they start at 6:30 p.m. and run through the month. The outings, which are suitable for whitewater novices, will include a handful of unthreatening rapids and are a perfect way to decompress after work. Those going will meet at the Lock 10 parking lot next to the Clara Barton Parkway and the decision to paddle down from Lock 7 or from the put-in across from Old Angler's Inn will be made then. Non-members are welcome, as are paddlers in recreational kayaks (which don't require sprayskirts.) For more information, contact Mike High at 703-317-1827 or mike.high@starpower.net. . . .
